Multifocal primary CNS T cell lymphoma of the spinal cord.
The majority of primary central nervous system lymphomas (PCNSL) are of B cell origin, and those of T cell origin are a distinct rarity. Furthermore, spinal cord involvement of T cell PCNSL is extremely rare and only a small number of cases have been reported. The authors report a case of multifocal T cell PCNSL mainly involving the intramedullary (IM) portion ofthe spinal cord in a 57-year-old woman. Neurological examination showed right leg weakness and hypesthesia below the T10 level. Magnetic resonance images revealed multiple well enhancing masses in the IM portion ofthe cervical and thoracic spinal cord and the cerebellum. Cytological examination of the cerebrospinal fluid revealed no malignant cells. As the mass at the C7 level was the largest among multiple masses, open biopsy was performed at that level. Histopathological examination confirmed malignant peripheral T cell lymphoma, unspecified (PTCL-U), small- and medium-sized cell type. Clinical and laboratory investigations failed to reveal any evidence of lymphomatous deposits elsewhere in the body. After biopsy, the patient received cranio-spinal irradiation, which included the whole brain and the spinal neuraxis. The clinical course, pathological findings and treatments are discussed and a review of the literature included.
