Meningeal involvement in IgD myeloma with cerebrospinal fluid paraprotein analysis

Abstract

Myelomatous meningitis is a rare occurrence in multiple myeloma. We report 2 cases of documented IgD myeloma with cytologic evidence of meningeal involvement in 1 and detailed paraprotein analysis in both. The occurrence of meningeal involvement in this rare form of plasma cell neoplasm may be more common than previously thought.
