Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
Hydrocephalus is seen. Bilateral internal cerebral veins and the great cerebral vein are hyperdense, compatible with acute thrombosis. Hyperdense thrombus is also partially filling the superior sagittal sinus.
Case Discussion
Non-contrast CT brain shows hydrocephalus and hyperdense internal cerebral veins and great cerebral vein, compatible with acute thrombosis. Hyperdense thrombus is also partially filling the superior sagittal sinus.
A dense triangle sign is sometimes seen in thrombosis of the superior sagittal sinus. Dural sinus and cerebral vein thrombosis may occur as a complication of infections such as meningitis, and can cause complications such as venous hemorrhagic infarct.
