Please enable it to take advantage of the complete set of features! METHODS: We completed a retrospective review of infants born 34 weeks of gestation, diagnosed with vein of Labbé thrombosis, and/or infarction on (A, C) Right carotid injection; (B, D) left carotid injection, lateral and anteroposterior projections. MR Imaging Features of Isolated Cortical Vein Thrombosis: Diagnosis and Follow-Up 11 November 2008 | American Journal of Neuroradiology, Vol. On the other MR imaging sequences, the signal-intensity changes corresponding to the occluded vein decreased after 3 months in all patients. On T2*GE images, linear hypointensity is seen in the right precentral sulcus, due to MSE at site of the thrombosed veins (small arrow) and hypointense areas corresponding to cortical hemorrhages (long arrows). Crossref, Medline, Google Scholar; 12. Dababneh H, Hussain M, Moussavi M, Kirmani JF. Petechial hemorrhages (n = 3) or hematoma (n = 2) was present on T2*GE imaging in 5/8 patients. Hypointensity on T2*GE images of the thrombosed vein has been reported in only isolated cases.5,6,17,18 In 8 patients with ICoVT selected from a large series of CVT (6.3%), we found a typical MSE at the site of venous occlusion in all patients by using T2*GE imaging. A rare case of aseptic thrombosis of the right vein of Labbé in a young woman is reported. Deep cerebral venous thrombosis is a subset of cerebral vein thrombosis with similar risk factors and epidemiology. RG. ADC values normalized within the tissue after 3 months in all patients. Mild left-sided neurological deficits resolved almost completely. 1. The vein of Labbe is a relatively smaller vein which runs superficially and laterally. Utility of diagnostic cerebral angiogram in a patient with fluctuating aphasia and presumed left atretic transverse sinus on noninvasive imaging modalities. Username *. Jones BV(1).

The purpose of the Journal of the Belgian Society of Radiology is the publication of articles dealing with diagnostic and interventional radiology, related imaging techniques, allied sciences, and continuing education A rare case of aseptic thrombosis of the left vein of Labbé in a young woman is reported. • Cortical vein thrombosis: Thrombosis of the cortical veins refers to a thrombosis of the superficial veins of the cerebral convexities including the vein of Labbe. Accessibility 2021 Mar 9;96(10):492-493. doi: 10.1212/WNL.0000000000011502. Also, the offending vein is not always identified when small cortical veins are involved, presumably from recanalization after the subsequent insult by hemorrhage or infarct occurs. We do not capture any email address. The combination of MR imaging showing the thrombosed vessel and MR venography (MRV) demonstrating the nonvisualization of the same vessel is considered to be the best diagnostic tool in CVT.1–3 The signal intensity of venous thrombi on T1- and T2-weighted MR images varies according to the interval between the onset of thrombus formation and imaging. Their main clinical manifestations are presented in On-line Table 1. Cerebral venous thrombosis (CVT) should be considered in the differential diagnosis of all unexplained CNS disorders of sudden onset. Endovascular treatment of carotid cavernous fistulas (CCFs) via a transvenous approach is standard, but in rare cases this approach is challenging due to absence or thrombosis of the commonly used venous routes. In the acute stage (0–5 days), the signal intensity is predominantly isointense on T1-weighted images and hypointense on T2-weighted images and is presumably related to the appearance of deoxyhemoglobin in red cells within the thrombus. Presentation is often substantially more severe than superficial venous thrombosis and includes nausea, vomiting, headache, focal neurological deficit, loss of consciousness, neuropsychiatric symptoms, or seizures. Follow-up MR imaging showed that MSE remained detectable on the last examination (3–18 months), but its size was significantly reduced in 5/8 patients at 3 months (Fig 2B, -C) and markedly reduced in all patients with late MR imaging, at 1 year (3 patients) and at 18 months (1 patient). Thank you for your interest in spreading the word on American Journal of Neuroradiology. Among the 6 patients who did not have any lobar hematoma, hyperintense parenchymal lesions were detected on DWI in 5. MR imaging was performed 3–19 days after clinical onset (symptoms). Parenchymal signal-intensity changes were also assessed on the same sequences. Venous thrombosis can occur spontaneously or secondaryto trauma, infection or as a complication of surgery. Like deep cerebral vein thrombosis, cortical vein thrombosis occurs most often in combination with sinus thrombosis. f. Volume 26 Special Issue Leach et al S21. Background—We report a unique case of an acquired pial arteriovenous fistula occurring after an asymptomatic thrombosis of a superficial cerebral vein.. Case Description—A cerebral angiogram performed in a 51-year-old man with subarachnoid hemorrhage revealed a 10-mm ruptured anterior communicating artery aneurysm and a thrombosed left superficial middle cerebral vein. For personal accounts OR managers of institutional accounts. The occluded vein appeared as hyperintense in 3 patients, iso- to slightly hyperintense in 1 on T1, hypointense in 6 on FLAIR images, and as signal-intensity loss on DWI in 3. On T1-weighted imaging, the occluded vein appeared as hyperintense in 3 patients, isointense to slightly hyperintense in 1 (Fig 2B), and hypointense in 1 patient. Parenchymal hyperintensities on FLAIR and DWI (increased apparent diffusion coefficient [ADC]) were observed in close vicinity to the thrombosis in 6/8 patients. Cerebral venous thrombosis is located in descending order in the following venous structures: Major dural sinuses: Superior sagittal sinus, transverse, straight and sigmoid sinuses. ... Isolated thrombosis of the vein of Labbe – clinical and imaging features. All MR imaging data were reviewed by 2 readers (M.B. Diagnosis of cerebral venous thrombosis (CVT) is difficult due to its wide spectrum of clinical presentation. 2009 Feb;30(2):344-8. doi: 10.3174/ajnr.A1332. Parenchymal signal-intensity abnormalities were present in 7 patients at initial MR imaging. Patient 7. At follow-up, persisting signal-intensity abnormalities on T2*GE imaging were detected at the venous sites in all patients, whereas signal-intensity changes on T1- and T2-weighted images were no longer present.

The vein of Labbe is part of the superficial venous system, draining the lateral surface of the temporal lobe. This site needs JavaScript to work properly. DSA4. Dural venous sinus thrombosis for Radiology & Imaging . Unable to load your collection due to an error, Unable to load your delegates due to an error. Finally, the signal intensity in a chronic thrombus is typically isointense or hyperintense on T2-weighted and isointense on T1-weighted images. Importantly, no surgical craniotomy or inser-tion of a ventricular drain was performed. FOIA The vein of Trolard & Labbe The vein of Trolard/ Superior anastomotic vein Large vein which passes upward & backward over the cerebral hemisphere to enter the superior sagittal sinus in the parietal region. Colour Doppler sonography revealed no colour signals within lumen of vein or within thrombus. All patients were treated with heparin immediately after diagnosis. Based on the distribution of hemorrhagic infarction, this is most likely due to thrombosis of the vein of Labbé. The signal-intensity changes on FLAIR images were identified with the help of data on T2*GE imaging. On the last MR imaging examination (from 3 to 18 months depending on the patient), no signal-intensity abnormality was detected at the site of ICoVT on T1-weighted, T2-weighted, FLAIR, or DWI. Dural venous sinus thrombosis for Radiology & Imaging . Patient 8. Department of Radiology, AZ KLINA, Brasschaat, Belgium. Thrombosis of the vein of Labbé can occur in the neonatal period. Based on the distribution of hemorrhagic infarction, this is most likely due to thrombosis of the vein of Labbé. The developmental outcomes of infants who had vein of Labbé thrombosis are unknown as few studies of outcomes exist. To date, almost all previously reported cases have occurred on the left. In all patients, the presence of a typical magnetic susceptibility effect (MSE) (ie, a strong and obvious hypointense signal intensity encompassing the vessel lumen on T2*GE imaging) was assessed at each site of CVT after consensus between the 2 readers. The vein of Labbé is a superficial cortical vein, which drains the lateral surface of the temporal lobe. favour the diagnosis of vein of Labbé thrombosis. CT2. On the other hand, these findings also suggest that the observation of isolated MSE may indicate, in specific circumstances, a past thrombotic event and may be useful in performing a post hoc diagnosis of ICoVT. Transient statesof hypercoagulability from dehydration, oral contraceptives, andpregnancy or permanent hypercoagulability from genetic causes or chronicphysiologic states such as malignancy are risk factors. B, On the T2*GE image (same plane as in Fig 1A), note reduced but still visible MSE at the site of venous thrombosis (arrow), as well as petechial hemorrhages. A, Follow-up at month 3 reveals cortical hyperintensity on the T1-weighted image due to petechial hemorrhages. In all cases, tissue signal-intensity changes were detected close to the occluded vein with T2*GE imaging. 2005 Sep;25(9):605-7. doi: 10.1038/sj.jp.7211298. Prognosis of cerebral vein and dural sinus thrombosis: results of the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT). In our patient, a cerebral venous thrombosis (CTV) was unable to identify vein of Labbe thrombosis, requiring eventually a magnetic resonance imaging (MRI) with and without contrast to identify the culprit etiology. From: 1. Enter multiple addresses on separate lines or separate them with commas. We report the clinical and MR imaging results obtained by using standard MR imaging sequences combined with T2*GE and diffusion-weighted images (DWIs) at the time of diagnosis and during follow-up in 8 consecutive patients with ICoVT. In 2 patients (patients 7 and 8), an intracerebral hematoma was detected both on T2*GE and T1-weighted images (Fig 4A, -B). Patient 8. The persisting signal-intensity changes of thrombosed veins on T2*GE images previously reported several months after onset in different types of CVT7 are presumably related to hemosiderin deposits within old clots or venous walls. Prevention and treatment information (HHS), National Library of Medicine Username *. We thank Philippe Burty for technical assistance. We assessed the presence of a magnetic susceptibility effect (MSE) on T2*GE imaging at each site of cerebral venous thrombosis and the presence or absence of a normal flow void and iso-, hypo-, or hyperintense signal intensity on T1, T2, diffusion-weighted imaging (DWI), and fluid-attenuated inversion recovery (FLAIR) images. Demonstration of the thrombus in the dural sinus or vein is pathognomonic of CVT. MR imaging examinations were performed at the time of diagnosis and during the follow-up at 15 days (4 patients), 3 months (all patients), 6 months (6 patients), 12 months (3 patients), and 18 months (1 patient). Findings suggested vein of Labbe thrombosis and were confirmed with MRI and magnetic resonance venography (MRV) (figure 2). MRI/V3. At the time of diagnosis, all patients had headache, which was the only symptom in 1 patient. The lumen of a previously permeable paraumbilical vein is completely filled with hypoechoic material representing occlusive thrombus. Both of our patients with lobar hemorrhages presented with a thrombosed vein of Labbé. In addition to MR imaging examination, DSA was performed in patients 1, 5, 7, and 8. BACKGROUND: The vein of Labbé is a superficial cortical vein, which drains the lateral surface of the temporal lobe. Isolated vein of Labbe thrombosis is rare. The combination of a nonspecific clinical picture with an atypical lesion on CT may favour the diagnosis of cortical venous thrombosis.

In addition, although a moderate-to-intense hyposignal of the thrombosed vein was also detected on FLAIR images in 6 patients within the first week after clinical onset (not previously detected), the detection of MSE was found helpful to discern these subtle vascular signal-intensity changes. Overview; Fingerprint; Original … The relatively benign clinical course, distribution of initial parenchymal involvement, and regression of lesions at follow-up MR imaging were close to features previously reported in the rare cases of ICoVT involving the vein of Labbé, despite initial clinical worsening and MR imaging signs of herniation.11–14 Therefore, our results emphasize that ICoVT should be considered as a potential cause of lobar hemorrhage, and they suggest that T2*GE is then crucial to reach the diagnosis and for therapeutic decisions. The diagnosis can be confirmed on computed tomography veno - graphy. This suggests that the sole presence of a venous MSE on T2*GE images cannot be used in isolation for diagnosis of active ICoVT and that the other sequences and/or follow-up data are still useful to estimate the thrombus age. A coexistent remote dural arteriovenous fistula at the junction of the left vein of Labbe´ and the transverse sinus was also present on the follow-up cerebral angiogram. Thrombosis of the vein of Labbé can occur in the neonatal period. Bethesda, MD 20894, Copyright The combination of the clinical setting with the findings on the non-enhanced CT may favour the diagnosis of vein of Labbé thrombosis. 1999 Dec 16-31;29(12):1355-6.

Sassi SB, Touati N, Baccouche H, Drissi C, Romdhane NB, Hentati F. Cerebral venous thrombosis: a tunisian monocenter study on 160 patients. During the follow-up, all cerebral tissue signal-intensity changes on T1, T2, and FLAIR images decreased both in volume and intensity. In contrast, the parenchymal abnormalities observed with the other MR imaging sequences decreased both in volume and intensity. An extra-axial band corresponding to the thrombosed vein of Labbé appears as a marked MSE on T2*GE image (A, arrow), isointense on T1 (B, arrow), hypointense on FLAIR sequence (C, arrow), and as a signal-intensity loss on DWI (D, arrow). Deep cerebral venous thrombosis is a subset of cerebral vein thrombosis with similar risk factors and epidemiology. In ICoVT, signal-intensity changes on T1- and T2-weighted images, identical to those observed in sinus thrombosis, have been previously detected in cortical veins.

The left Labbe vein has been most often involved. The signal from the thrombus within the dural sinus or cortical vein is variable (Table 1).4 However by the time most patients are scanned the thrombus shows hyper-intense signal both on T1 as well as T2 weighted images (Figure 2 and 3). Digital subtraction angiography, venous phase. Author(s): Stýblo-Sramek, D. ; Temmerman, G. ; Verbist, B.M. Cerebral venous thrombosis, which includes dural sinus thrombosis and the more unusual isolated cortical venous thrombosis (CVT), is an established cause of parenchymal hemorrhage (1–3).Subarachnoid hemorrhage (SAH) is a rare presentation of cerebral venous thrombosis … Evaluate the prevalence of Labbé vein thrombosis (LVT) and its liability for the lesions observed in the case of associated ipsilateral transverse sinus thrombosis (TST). Risk factors for the development of cortical vein thrombosis include thrombophilia, pregnancy or peripartum, malignant neoplasm, oral contraceptive use, and central nervous system infections. Among them, isolated thrombosis of the vein of Labbe has been rarely reported. Having sinus or cerebral vein thrombosis increases the risk for developing other vein clots, mostly deep vein thrombosis (DVT) of the legs and pulmonary . - "Isolated left vein of Labbe thrombosis" For personal accounts OR managers of institutional accounts. 10 However, because the number and location of these veins are highly variable, these changes are difficult to visualize. Despite this worsening, all patients improved, with a full clinical recovery in 6 and incomplete recovery in 2 (patients 7 and 8) at 1 year after diagnosis. Stroke 2004;35(3):664–670. MATERIALS AND METHODS: MR imaging examinations were performed in 8 patients with ICoVT (MR venography was performed in … [Hemorrhagic infarct as a result of cerebral venous thrombosis as a complication of cirrhosis].

Venous infarcts (3) - vein of Labbe Another typical venous infarction is due to thrombosis of the vein of Labbe. Careers. ADC was increased from 12% to 22% in hyperintense areas on DWI in the 5 patients with hyperintensities. Radiology. A transient worsening was observed in 4 patients (patients 2, 3, 7 and 8, see On-line Table 1). For reasons unknown, thrombosis of the left vein of Labbé occurs significantly more frequently than the right. Vein of Labbe MR Venogram Brain Named after 17th century French surgeon Charles Labbé who described it in his 3rd year of medical school. Cerebral venous thrombosis was suggested by computed tomography and confirmed by angiography. Mild left-sided neurological deficits resolved almost completely. It is one of the superficial cortical veins connecting the middle cerebral vein to the transverse sinus, and drains the adjacent temporal lobe. 30, No. Thrombosis of the vein of Labbé can occur in the neonatal period. doi: 10.1016/j.pediatrneurol.2017.03.015. C−E, On coronal images in the same plane, the aspect of a cord sign is visualized at the surface of the cortex, hyperintense on T1- and T2-weighted images (arrow, C and D) and hypointense on the T2*GE image (E). 8600 Rockville Pike All patients with ICoVT seen in our institution from April 2002 through September 2006 were selected on the basis of the following criteria: 1) history and clinical manifestations compatible with or suggestive of CVT, 2) MR imaging features at first examination or during follow-up examinations suggestive of CVT in the absence of sinus thrombosis, and 3) clinical improvement and significant reduction of MR imaging signal-intensity abnormalities under anticoagulant treatment. MATERIALS AND METHODS: MR imaging examinations were performed in 8 patients with ICoVT (MR venography was performed in all patients and digital substraction angiography in 4) at the time of diagnosis and during the follow-up at 15 days (4 patients) and at 3 (8 patients), 6 (6 patients), 12 (3 patients), and 18 months (1 patient). Isolated cortical vein thrombosis (ICVT) accounts for less than 1% of all cerebral infarctions. cerebral vein thrombosis and the subsequent pial arterio-venous fistula. Altogether, the present data underline the additional and crucial diagnostic value of T2*GE for the diagnosis of ICoVT, especially at the early phase. Thrombosis of right vein of Labbe: Author information: (1)Department of Radiology, Leiden University Medical Center (LUMC), Leiden, the Netherlands.

Privacy, Help On T2-weighted images, the clot was either hypointense in 4/6 or isointense in 2/6 patients. MRI/V3. Although portal vein thrombosis is uncommon, this complication should be considered in dogs with a variety of abdominal or systemic disorders. The left Labbe vein has been most often involved.1 The vein of Labbe drains the lateral tempo-ral lobe and empties into the transverse sinus.1,2 Thrombosis can cause temporal lobe hemorrhagic infarction, hemorrhage, or edema. Key-word: Cerebral blood vessels, thrombosis. The vein of Labbé, described by French surgeon Charles Labbé in the 19th century, is also known as the inferior anastomotic vein. Boukobza M, Crassard I, Bousser MG, Chabriat H. AJNR Am J Neuroradiol. T2*GE images were obtained in all subjects (TR, 560 ms; TE, 15 ms; 20 sections; sagittal and/or axial and coronal planes; section thickness, 5 mm; matrix size, 256 × 192; FOV, 24 × 24 cm) as well as 2D time-of-flight MRV. The developmental outcomes of infants who had vein of Labbé thrombosis are unknown as few studies of outcomes exist. MRI findings of 58 consecutive patients (≥ 18 years) with acute LVT and TST (group 1) were compared with those of 149 patients with acute TST-no LVT (group 2) observed during the same period. A and B, Initial MR imaging at day 7. 12 Scopus citations. Finally, increased ADC in the cerebral tissue was consistent with the presence of vasogenic edema as also suggested by the complete recovery of hyperintense lesions on FLAIR images in the same area parallel to the clinical improvement as previously observed.20–22. At the parenchymal level, the presence of hyper-, iso-, or hypointense signal-intensity abnormalities was also assessed on each sequence, including DWI.

C, At month 12, T1-weighted imaging findings are normal on T2*GE image (arrow); MSE is still identified. 1. CONCLUSIONS: On T2*GE imaging, MSE of hemoglobin products within the thrombus was observed both at the early and late phases of ICoVT and appears to be of high diagnostic value compared with the other signal intensity changes detected on standard MR imaging. In contrast to the transient signal-intensity changes on standard MR imaging, the cortical venous MSE observed on T2*GE images can persist several months and possibly years after the diagnosis and treatment of ICoVT. 2018 Jul-Sep;21(3):203-208. doi: 10.4103/aian.AIAN_470_17. In 4 patients, ICoVT involved anastomotic veins, the Trolard vein in 2 patients (patients 3 and 8), and the vein of Labbé in 2 others (patients 5 and 7), with extension in 1 patient to the superficial Sylvian and frontal veins (patient 7). Patients with pathology in intracranial venous structures or with inadequate image quality of the venous system were excluded.
