Paraparesis following intrathecal cytosine arabinoside: a case report with neuropathologic findings.

Abstract

A 65-year-old white male with acute myelogenous leukemia received whole brain irradiation (2550 rads) and intrathecal cytosine arabinoside for CNS prophylaxis. Bone marrow remission had been previously achieved with systemic chemotherapy (vincristine, Adriamycin, prednisone, and cytosine arabinoside). Two weeks following the last intrathecal cytosine arabinoside treatment, the patient developed a spastic paraparesis requiring the use of a walker. A gas myelogram was normal and CSF examination revealed a protein of 50 mg/100 ml but was otherwise unremarkable. Five months later, the patient had improved in that he could stand on his own. A relapse of his leukemia subsequently occurred and the patient died the following month. Striking degenerative changes were found in the spinal cord at postmortem examination. These included microvacuolization, axonal swellings, and loss of myelin with scattered macrophages laden with fat.
