Abstract

A case is reported here of brain abscess due to Streptococcus sanguis in association with multiple pulmonary arteriovenous fistulas. A 19-year-old male who had been diagnosed in 1988 as pulmonary arteriovenous fistulas was admitted to our hospital for repeated epistaxis, headache, and vomiting. A brain abscess which was diagnosed using various roentogenologic examinations, worsened despite conservative therapy. Additional surgical drainage was performed; S. sanguis was isolated from the drainage fluid. After drainage, clinical symptoms gradually improved with no subsequent neurological dificits.<BR>We have formulated the following hypothesis regarding the mechanism of abscess formation in this case: S. sanguis invaded from a ruptured nasomucosal vein, forming a septic emboli in the blood flow, which passed through a pulmonary arteriovenous shunt and led to the formation of a brain abscess which established a metastatic presence in the cerebral tissue.
