title: Primary meningeal lymphoma of T-cell origin: a rare presentation of primary central nervous system lymphomas.
abstract: Primary meningeal lymphoma is a rare clinical entity. Central nervous system infiltration by systemic lymphoma should always be excluded. Diagnosis can be difficult, and prognosis is usually poor. Most are of B-cell origin. We present the case of a young man with a primary meningeal lymphoma of T-cell origin. He was treated with systemic chemotherapy with high-dose methotrexate and cytarabine and intraventricular chemotherapy. He had a clinical improvement and a complete remission, with a long overall survival. There is no standard treatment for this rare disease. Traditionally, treatment has been based in craniospinal radiation therapy and intrathecal chemotherapy, with poor overall results. More recently, systemic chemotherapy with high-dose methotrexate has been advocated, which could avoid the long-term toxicity of craniospinal radiation therapy, and could improve the prognosis of these patients.
