Review Case Reports
[Cauda equina syndrome due to recurrent malignant lymphoma of the spinal cord. A case report].
A 50-year-old man noticed a mass in the right cervical region and presented to our hospital. He underwent biopsy of a cervical lymph node, which revealed non-Hodgkin's lymphoma (diffuse large B cell, lymphoblastic type) histologically. He was treated with chemotherapy (CHOP) and radiation, and achieved complete remission. ⋯ After the treatment the mass in the cauda equina disappeared and the neurological symptoms in his legs resolved. It is rare for malignant lymphoma to recur in the spinal cord, particularly the cauda equina. It is well known that cauda equina syndrome can be caused by vertebral lesions and primary spinal cord tumors, but it is also necessary to keep malignant lymphoma of the cauda equina in mind.
