Infectious intracranial aneurysm and multifocal stroke in endocarditis. Coronal computed tomography angiography (CTA) of intracranial circulation (A), axial diffusion-weighted (DWI) magnetic resonance imaging (B), and axial T2 fluid-attenuated inversion recovery (FLAIR) imaging (C) from a 54-year-old right-handed female who was found down by her family. CTA shows infective intracranial aneurysm (arrow) in the right middle cerebral artery territory, and DWI and FLAIR demonstrate innumerable bilateral embolic infarcts. The patient was found to have methicillin-sensitive Staphylococcus aureus bacteremia and endocarditis of the mitral valve, septic shock, and multiorgan failure. Despite antibiotics, the patient remained too unstable for surgical intervention and died 20 days after presentation.
