Infectious Endocarditis Associated with Subarachnoid Hemorrhage, Subdural Hematoma and Multiple Brain Abscesses

Abstract

Hemorrhagic stroke is a complication of infectious endocarditis (IE), and severe hemorrhage accompanies Staphylococcus aureus IE during early uncontrolled infection. However, subarachnoid hemorrhage (SAH) or subdural hematoma is rare. A case of S. aureus IE associated with SAH and subdural hematoma in the early stage is reported. A 54-year-old man with a history of mitral valve prolapse presented with fever. Two days after the onset, he fell into a confused state with convulsion and left hemiparesis. He became comatose and brain CT and MRI demonstrated SAH and subdural hematoma with severe right hemisphere swelling. Multiple brain abscesses were also observed. No septic aneurysm was detected by cerebral angiography.
