Abstract
Astrocytomas of Conus-Cauda equina region are rare. Astrocytomas, which are intramedullary tumors, may rarely have an extramedullary component. However, primary intradural extramedullary astrocytomas are extremely rare, with very few cases reported in the literature. We describe a giant extramedullary pilocytic astrocytoma of Cauda equina in a 20-year-old male. To the best of our knowledge, this is the first report of such a case in the available literature. This case highlights the fact that astrocytomas can be primarily extramedullary and emphasizes the need to consider pilocytic astrocytoma in the differential diagnosis of cystic Cauda equina tumors.
