Cerebral Venous Sinus Thrombosis



Cerebral venous sinus thrombosis (CVST) is an uncommon but life-threatening emergency. It is an important cause of stroke especially in children and young adults that requires quick diagnosis and rapid treatment.
The most common clinical manifestations are headache, seizures, altered consciousness and neurologic focal signs on physical examinations. Underdiagnosis or misdiagnosis of cerebral venous thrombosis can lead to severe consequences including hemorrhagic infarction and death.
Imaging can vary from the most subtle findings of sulcal effacement to the extremely complex with concomitant infarct, vasogenic edema often complicated by hemorrhage; thus, making cerebral venous thrombosis a challenging diagnosis to both radiologists and clinicians.
In this article 28 patients with cerebral venous-sinus thrombosis, who referred to Parto Teb Azma and Tabesh Parto Medical Imaging Centers in Qom from 2015 until the end of 2017 are reviewed and their radiologic findings are evaluated. Both CT and MRI are used to diagnose CVST. Since MRI and MRV are the most common tools for diagnosis, this article is focused on MRI findings in CVST with evaluation of different pulse sequences and MR venography.
