Multiple plasma cell granulomas of the central nervous system: case report.

Abstract

Plasma cell granulomas of the central nervous system are exceedingly rare. Of the six well-documented cases that have been published to date, five plasma cell granulomas were intracranial and one was located in the spinal meninges. Multiple plasma cell granulomas of the central nervous system have not previously been reported. We now report a patient who had two plasma cell granulomas in the spinal meninges and one in the anterior cerebral falx. The histological findings that differentiate this rare lesion from other central nervous system lesions, such as plasmacytoma and meningioma, are discussed with a review of the literature.
