title: Extensive subdural mass.
abstract: An unusual case of a 62-year-old man with focal seizures, tinnitus, and progressive left hemiparesis due to an extensive subdural plasma cell granuloma is presented. Five-year clinical and radiologic follow-up demonstrating the chronic yet progressive nature of this granuloma is presented. This is the first report of focal calcification seen in an intracranial plasma cell granuloma. The imaging, neuropathologic, and clinical characteristics of this rare lesion are reviewed.
