title: Castleman's disease, plasma-cell type. Diagnosis of central nervous system involvement by cerebrospinal fluid cytology.
abstract: A case of Castleman's disease of the plasma-cell type is reported in which central nervous system (CNS) involvement was diagnosed by cerebrospinal fluid (CSF) cytology. The patient had multicentric disease with constitutional symptoms, immunologic abnormalities and peripheral blood cytopenias requiring cytotoxic agents and steroids for treatment. CNS symptoms and diagnostic cytologic findings in CSF occurred in the absence of morphologic lesions demonstrable by computed tomography or magnetic resonance imaging of the brain.
