Primary intramedullary non-Hodgkin's lymphoma in an immunocompetent child.

ABSTRACT

STUDY DESIGN: Case report. OBJECTIVES: Primary intramedullary spinal cord lymphoma is a rare entity. Studies have shown that there is a recent increase in the number of patients regardless of the status of the immunity. High index of suspicion should be kept in all patients with intramedullary tumors. Multidisciplinary approach at the earliest is required for best outcomes. SETTING: Department of Neurosurgery, Medical Oncology, Pathology and Radiation oncology. Nizam's Institute of Medical Sciences, Hyderabad, India. METHODS: We describe the case of an 11-year-old boy who presented with paraparesis and sensory loss below T10 level. On imaging, the dorsal spine showed intramedullary lesion mimicking an astrocytoma. RESULTS: Surgical decompression of the tumor was done and histopathology showed non-Hodgkin's lymphoma, diffuse large B-cell type. There were no findings suggestive of congenital or acquired immunodeficiency. After complete staging evaluation, we instituted chemotherapy with modified DeAngelis protocol. At 2 years post treatment, he is in complete remission with near normal neurological status. CONCLUSIONS: Intramedullary spinal cord diffuse B-cell lymphoma in a pediatric age group is very rare and hence requires a high index of suspicion in patients presented with myelopathy. The outcomes are encouraging with current multidisciplinary approach.
