Case Report: Neoplastic Meningitis with Eosinophilic Pleocytosis in Hodgkin’s Disease: A Case with Cerebellar Dysfunction and a Review of the Literature

A 31-year-old man had Hodgkin’s disease (stage IIA, nodular sclerosis) in apparent remission after radiotherapy. Nine months after the diagnosis of Hodgkin’s disease, he developed neoplastic meningitis with eosinophilic pleocytosis and neurologic findings suggestive of peri-fourth ventricle infiltration. Morphologic and surface marker analysis of cerebrospinal fluid cells showed large numbers of Tlymphocytes and Reed-Sternberg variant cells positive for CD 15, the Lex hapten expressed on myeloid cells and on a variety of malignant cells. Therapy with intrathecal methotrexate, oral dexamethasone, and cranial irradiation resulted in prompt resolution of his cerebrospinal fluid abnormalities and neurologic deficits. Ten months after the diagnosis of eosinophilic meningitis, systemic relapse of Hodgkin’s disease occurred in right iliac and inguinal lymph nodes. The diagnosis, pathogenesis, and therapy of this unusual complication of Hodgkin’s disease are reviewed.
