Abstract

Introduction: Cerebral venous thrombosis (CVT) is an uncommon type of venous thromboembolism that primarily affects young adults and children. CVT has three subtypes that frequently coexist: cortical vein thrombosis, deep cerebral vein thrombosis, and cerebral venous sinus thrombosis. Females are affected three times more frequently than males due to gender-related risk factors such as oral contraceptives and pregnancy. CVT has a wide range of nonspecific clinical manifestations, from headache to coma. Prompt evaluation is required because early anticoagulation can reverse acute CVT and reduce complications. CVT can be diagnosed using either an MRI with MR venography (MRV), CT venography (CTV), or catheter angiography. A filling defect is noted within the thrombosed cerebral vein or dural sinus on CTV or MRV. An acute venous thrombus can appear as a spontaneous hyperattenuation on a non-contrast CT (NCCT). The addition of venous attenuation measurement to the NCCT may improve its diagnostic value.

6- Aim: This study was conducted to assess the role of quantitative non contrast computed tomography evaluation in acute cerebral venous thrombosis.
