Meningioma associated with abscess formation--a case report.

A rare case of meningioma associated with both intratumoral and peritumoral abscess formation occurred in a 38-year-old man presenting with signs and symptoms of elevated intracranial pressure, intracranial infection, and right temporal pole mass lesion. The mass lesion was totally removed, revealing a meningioma. Group B streptococcus and peptostreptococcus were cultured from both the tumor and peritumoral white matter. Hematogenous spread of the organisms related to recent dental work was the likely mechanism.
