Cerebral venous thrombosis on magnetic resonance imaging

(A) Axial post-contrast T1-weighted MRI sequence shows filling defect consistent with acute thrombus in superior sagittal sinus (thick arrow) and superior cerebral veins (arrows).

(B) Time-of-flight sequence on MR venogram shows absent venous flow in superior sagittal sinus (arrows).

(C) Axial susceptibility-weighted MRI sequence shows thick and hypointense thrombus in superior sagittal sinus (thick arrows) and superior cerebral veins (arrows).
