AU - Kumar, Vinodh A. PY - 2012/12. Three-dimensional integral image from CT venography (lateral view) shows the anastomotic vein of Trolard (AVOT) draining into the superior sagittal sinus (SSS), the anastomotic vein of Labbé (AVOL) draining into the transverse sinus (TS), and the superficial middle cerebral vein (SMCV). Findings suggested vein of Labbe thrombosis and were confirmed … High hematocrit can be a physiologic cause of hyperdense sinus; Hyperdense cortical veins (“cord” sign) possibly involving the veins of Labbé and Trolard; Venous infarct (present in 50% of dural venous thrombosis) – location clues: A quartet of lateral sinus thrombosis, extradural abscess, subdural abscess and occipital abscess: complications of acute mastoiditis in a pre-adolescent child. The central vein, precentral vein, a small frontal vein, and the midfrontal vein were involved respectively in patients 1, 2, 4, and 6. 1993;35(3):202-4. doi: 10.1007/BF00588494. 1).CVT most commonly affects the frontal cortical veins, followed by the parietal veins. Other signs are: 1) There are no normal veins seen draining the temporal convexity — this cannot possibly be normal. AU - Shroff, Girish. Computed tomographic imaging of cerebral venous thrombosis. Dorndorf D, Wessel K, Kessler C, Kömpf D. Neuroradiology. A rare case of aseptic thrombosis of the right vein of Labbé in a young woman is reported. CT venogram demonstrated a thrombus in left vein of Trolard, extending into the superior sagittal sinus (c). Comparable to isolated deep venous thrombosis, isolated CVT seems to be rather rare and has only been described in case reports and small case series. 2018 Oct-Dec;4(4):188-190. doi: 10.4103/bc.bc_34_18. Discussion. Absence of filling of 1 or more of the ipsilateral superficial middle cerebral vein, vein of Trolard, vein of Labbé, basal vein of Rosenthal, and internal cerebral vein, evaluated on venous maps generated from baseline CTP, was identified as absent ipsilateral venous filling (AIVF). The Rolando is a named vein, running by definition in the Rolandic sulcus, anterior to Trolard. An epidural abscess was suspected on pre-operative CT scan. Clipboard, Search History, and several other advanced features are temporarily unavailable. This was confirmed by MR venography (figure 1, D, E) and digital subtraction … The provisional diagnosis was viral encephalitis. In the early stage there is non-enhancement of the thrombosed vein and in a later stage there is non-enhancement of the thrombus with surrounding enhancement known as empty delta sign, as discussed before. Clipboard, Search History, and several other advanced features are temporarily unavailable. The veins drain into a larger central vein. Y1 - 2012/12 Epub 2012 Jul 28.

In most cases, the vein of Labbé drains into the lateral third or midportion of the transverse sinus, providing the surgeon with a wide exposure. Based on the surgical finding, we determined that this misdiagnosis was due to a vascular variant, the occipitotemporal vein (vein of Labbe) that masqueraded as an abscess on the CT scan.

Some doctors refer to them as caput medusae, a Latin term that means head of Medusa because the clump of veins resembles snakes on the head of the Greek mythological character named Medusa. Deep cerebral venous thrombosis is a subset of cerebral vein thrombosis with similar risk factors and epidemiology. Transient statesof hypercoagulability from dehydration, oral contraceptives, andpregnancy or permanent hypercoagulability from genetic causes or chronicphysiologic states such as malignancy are risk factors.
