Acute subdural hematoma caused by an unruptured, thrombosed giant intracavernous aneurysm

Acute subdural hematoma (SDH) is an infrequent complication after aneurysmal subarachnoid hemorrhage. SDH associated with unruputed intracavernous aneurysm has never been reported.
Single patient case report and review of relevent literature.
A 65-year-old woman with an unruptured, thrombosed giant intracavernous aneurysm developed an acute SDH 2 days after admission for cavernous sinus syndrome. Despite emergent evacuation of the SDH, the patient never regained consciousness because of brain herniation.
Acute SDH is a rare complication of ruptured, giant intracavernous aneurysms. Erosion of the cavernous sinus wall by acute enlargement of the aneurysm after thrombosis is the proposed mechanism for development of the SDH.
