Ruptured mycotic aneurysm presenting as an intraparenchymal hemorrhage and nonadjacent acute subdural hematoma: case report and review of the literature

Abstract

The case of a mycotic aneurysm presenting as an intraparenchymal hemorrhage and acute subdural hematoma is described. A 36-year-old man with a history of headaches and fever presented in coma. Brain computed tomography scan revealed a left occipital intraparenchymal hemorrhage and a nonadjacent acute subdural hematoma that was evacuated. Angiography demonstrated an aneurysm on the distal branch of the left posterior cerebral artery consistent with a mycotic aneurysm. This case and a review of the literature are discussed.
