Primary intramedullary spinal cord lymphoma. Magnetic resonance findings.

We report a case of an imunocompetent man who developed primary spinal intr amedullary malignant lymphoma. This condition occurs in about 0.9 p. 100 of primary central nervous system non-Hodgkin lymphomas in non-AIDS patients. Magnetic resonance imaging was nonspecific but suggestive. Like the brain localization, prognosis is poor. Because of the high frequency of recurrenc e, usually confined to the central nervous system with neuraxis disseminati on, treatment must be delivered to the entire neuraxis. But more effective treatment strategies with radiotherapy-chemotherapy combinations will be ne eded. Feasbility and toxicity patterns remain to be determined.
