[A Case of Subdural Empyema with Cerebral Arteritis and Brain Ischemia in the Middle Cerebral Artery Distribution, Secondary to Odontogenic Maxillary Sinusitis].

We present a rare case of subdural empyema with cerebral arteritis and brain ischemia in the middle cerebral artery distribution secondary to odontogenic maxillary sinusitis. A 32-year-old man was admitted to our hospital because of high fever and generalized convulsions. Computed tomography(CT)and magnetic resonance imaging(MRI)showed subdural empyema at the left convexity, with a small amount of air.
