Info

CT venography demonstrates hypoattenuating thrombus in the posterior sagittal sinus, the straight sinus, as well as the transverse and sigmoid sinus especially on the left, extending into the left jugular vein. The "empty delta sign" is visible on axial scans at the level of the posterior superior sagittal sinus.
Case Discussion
This female patient presented with paroxysmal headache. The patient was taking oral contraceptives at the time, which along with her age and gender placed her in a high-risk group for dural sinus thrombosis.
