Abstract

Primary CNS lymphoma (PCNSL) which is localized in the cauda equina of the spinal cord is very rare. A 75-year-old man had pain in both legs and gait disturbance for the last 45 days. Painful paresthesia and weakness in both legs worsened during a one month period and he was unable to stand up by himself. In a physical examination, lym-phadenopathy nor organomegaly was found. A neurological examination revealed a dominantly proximal muscle weak-ness of the lower extremities. All modalities of sensation were decreased in both legs and a Romberg test was found positive. A CSF cytology demonstrated a large B-cell lymphoma. Following an extensive evaluation of the patient, the lymphoma was found to be limited in the cauda equina. The patient was treated with systemic dexamethasone. After the treatment, his symptoms were improved and a follow up lumbar spine MRI showed shrunken cauda equina lesions.
