Rare Concurrence of Two Different Intraspinal Tumors at an Unusual Site: Ependymoma and Schwannoma

Abstract

Ependymoma has been typically described as an intramedullary tumor which is derived from ependymal cells. Intradural extramedullary spinal ependymomas are extremely rare. Hereby, we present a case report of a patient was diagnosed with an intradural extramedullary spinal tumor extending from D8-D9 level. Patient underwent gross total resection of the tumor. The tumour was diagnosed as a collision tumor, i.e., Ependymoma with Schwannoma like areas on histopathological examination, later confirmed by immunohistochemistry.
