PRIMARY EWING'S SARCOMA OF SPHENOID BONE EXTENDING TO BRAINSTEM; AN ORDINARY TUMOUR AT AN EXTRAORDINARY LOCATION AND INVOLVEMENT

Abstract

Ewing's sarcoma (ES) is the 2nd primary bone tumor of childhood, mostly located in the lower extremities. The incidence of primary cranial ES is <1%. Our patient is 9 years old female who has intracranial primary ES extending from the sphenoid bone corpus to the clivus border. This is a rare case of childhood that's originating from the sphenoid bone and spreading to such a very large intracranial area. Our aim is to provide data on the clinical and therapeutic course of a rare case.
