dural sinus thrombosis in fetus

Neuropediatrics, 2012. CASE: Second-trimester fetal ultrasonography and MRI demonstrated a large T2-hypointense mass centered at the level of the torcular Herophili consistent with complete thrombosis of a dural sinus malformation. Most cases have been terminated without long-term follow-ups. All the mothers undertook the prenatal magnetic resonance (MRI) imaging because of the intracranial space-occupying lesions discovered by prenatal ultrasound. We report a case of fetal dural sinus thrombosis. Thrombosis of a dural sinus malformation is mainly located supratentorially and pres-ents a wide range of dimensions. When many dural sinuses are occluded, a life-threatening increase in intracranial pressure can result. Avascular, supratentorial, hyperechogenic mass in the posterior fossa above the cerebellum, surrounded by a triangular sonolucent area (the dilated venous sinus). Thrombosis of the fetal dural sinuses is rare. A postnatal diagnosis of thrombosis in the dural sinus was established by magnetic resonance imaging and venography. Three of the six cases delivered vaginally with favorable sonographic … A specific type of midline dural sinus thrombosis (DST) at the torcular Herophili with extension into the superior sagittal sinus (SSS) was initially seen on fetal US and was referred to fetal MRI for definite diagnosis and better delineation. Mark Ebert. CASE: Second-trimester fetal ultrasonography and MRI demonstrated a large T2-hypointense mass centered at the level of the torcular Herophili consistent with complete thrombosis of a dural sinus malformation. Results: Fetal ultrasound and MRI obtained between 19 and 23 weeks gestational age demonstrated in all cases dilation of the dural sinuses. Thrombi within these dural sinus malformations can develop while in-utero, and can be visualized by ultrasound in fetal life.
