Fig 3. A 23-year-old male patient presenting with headache, amnestic aphasia, and visual disturbances (patient 4). MR imaging and MDCTA, performed on a 4-row-detector system, demonstrate a thrombosis of the left transverse (arrows) and sigmoid sinuses.
A, Axial T1-weighted MR depicts hyperintense, thrombotic material in the left transverse sinus.
B, C, 2D time-of-flight MR venography shows no flow void in the left transverse and sigmoid sinuses.
D, Coronal sections of MIP reformations demonstrate a filling defect in the left transverse sinus.
