Abstract

A 45-year-old woman presented with extensive deep cerebral venous thrombosis (DCVT) identified by typical direct thrombosed sign in the internal cerebral vein, vein of Galen, and straight sinus on both computed tomography and T₂*-weighted magnetic resonance imaging. Moreover, rare direct sign, probably of the direct lateral vein, was also obtained. Direct sign of the thrombosed vein or sinus is important for the diagnosis of DCVT. The present case indicates the usefulness of attenuated vein sign and T₂*-weighted imaging for the diagnosis of direct thrombosed vein in patients with DCVT.
