Primary central nervous system lymphoma (PCNSL) accounts for 1% of all lymphoma diagnoses and as many as 6% of all central nervous system (CNS) tumors. Most cases of PCNSL are of B-cell type; few are of T-cell lineage. PCNSL mainly occurs intracranially; primary spinal-cord lymphoma only occurs rarely. Moreover, intramedullary presentation without intracranial lesions is virtually unknown. Herein, we present a case of primary T-cell CNS lymphoma limited to the intramedullary spinal cord in an 82-year-old white man, along with a review of the literature on this condition and similar conditions.
Keywords: CNS T-cell lymphoma; Primary CNS lymphoma; primary intramedullary spinal cord lymphoma.
