CT angiogram of the brain and neck with contrast demonstrated partial obstruction of the right transverse sinus with complete obstruction of the right sigmoid sinus and jugular vein (Figure 1). There was nonvisualization of the entire right jugular vein (Figure 1).
Magnetic resonance imaging of the brain with contrast: T1- and T2-weighted images demonstrate occlusion of the right sigmoid sinus indicated by yellow arrow.

The most diagnostically significant finding was persistent thrombosis in the transverse and sigmoid sinuses bilaterally, extending down to the upper jugular veins (Figures 2 and 3).
