Case 13
History:
28 year old male with seizures and headache
Findings:
Non contrast CT shows high density appearing straight sinus and internal cerebral veins. Contrast CT shows enhancement of the deep gray structures.
Diagnosis:
Central venous thrombosis
Discussion:
Venus infarction is a complication of central venous or dural sinus thrombosis and may be seen in the temporal lobe if the transverse sinus, sigmoid sinus or vein of Labbe is occluded. Straight sinus thrombosis typically produces thalamic infarcts, while superior sagittal sinus thrombosis produces parasagittal infarcts. Up to 1/4 of venous infarctions are hemorrhagic. On NCCT a “hyperdense” sinus can be seen reflecting the blood clot. On ECCT a filling defect, known as the ” empty delta sign” can be seen.
