Non-Hodgkin Lymphoma of Cauda Equina: A Diagnostic Conundrum: Case Report.

Primary central nervous system lymphoma (PCNSL) is uncommon with scarce cases having involvement of the spinal cord. Cauda equina is unique in its location and shows very rare involvement by diseases pathologies. When the same occur, they pose a lot of diagnostic difficulties as the location is difficult to access with overlapping radiologic abnormalities. It is an unusual location for lymphomas to occur with only few cases reported in literature. The cauda equina lymphomas may mimic other entities which occur at that site. Histopathology is the gold standard for the same. Here, we report an unusual case of cauda equina lymphoma mimicking a myxopapillary ependymoma in a 50-year-old male.
