A 48-year-old normotensive woman with intact coagulation and a history of oral contraceptive use who presented with worsening headaches followed by a generalized tonic-clonic seizure. A and B, High probability NCCT demonstrates an acute left temporal IPH with associated hyperattenuation in the left transverse sinus evidenced in the coronal reformation (arrowhead). There is no associated IVH or SAH. There is also hyperattenuation within the left vein of Labbe (not shown). C, MIP image after calvarial segmentation of a CT venogram performed immediately after the CTA demonstrates nonopacification of the left transverse and sigmoid sinuses (arrowheads), with adequate opacification of the contralateral venous sinuses, consistent with dural venous sinus thrombosis.
