Prenatal diagnosis of torcular herophili thrombosis with unfavored outcome and review

Abstract

Prenatally diagnosed thrombosis of the torcular herophili is a rare described entity. There are about 50 cases described in the literature till now. We here discuss the radiological findings of dural sinus thrombosis at the torcular herophili with extension into the superior sagittal sinus demonstrated on fetal magnetic resonance imaging (MRI) at the second trimester. After birth, the infancy was followed up to sixth months with serial MRI. During this period there was moderate reduction in the size of the thrombus. There was not any underlying cause for the thrombus both in the mother and the infancy. Unexpectedly, the cranial MRI revealed the signs of cerebral atrophy at the age of sixth month. Regarding the cerebral atrophy in a prenatally diagnosed torcular herophili thrombus, there was not a sample of this combination in the literature before. In this presentation we discuss the radiologic and clinical findings of prenatally diagnosed torcular herophili within the review of the literature.
