چکیده

A 43-year-old woman, presented with headache, reduced visual acuity, for 5 days and bilateral papilledema. Non-enhanced cerebral computed tomography (CT) was normal. The venous angiography-CT revealed the empty delta sign within superior sagittal, right transverse and sigmoid sinuses, characterizing sinus thrombosis (Figure). The empty delta sign is a central intraluminal filling defect, representing a thrombus surrounded by contrastenhanced dural collateral venous channels. It can be seen in 25%-75% of sinus thrombosis, using wider window settings than those used for brain parenchyma. Most often, non-contrast CT is normal, hence the importance of using intravenous contrast when suspecting of dural thrombosis.
