FIG 2.

A, NCCT shows a subtle hyperdense thrombus in left transverse sinus. MR imaging of the brain: T1 postgadolinium images in axial (B) and sagittal (C) projections and MRV (D) with gadolinium showing sinus thrombosis of the torcula with extension to the bilateral, left-greater-than-right, transverse sinuses. E, Endovascular microcatheter venogram shows progression of thrombus throughout superior sagittal sinus. F, A postinterventional venogram shows improved patency after mechanical thrombectomy.
