Abstract
BackgroundGiant cell tumor is a benign but locally aggressive bone neoplasm which uncommonly involves the skull. The petrous portion of the temporal bone forms a rare location for this tumor.Case presentationThe authors report a case of a large giant cell tumor involving the petrous and squamous portions of the temporal bone in a 26 year old male patient. He presented with right side severe hearing loss and facial paresis. Radical excision of the tumor was achieved but facial palsy could not be avoided.ConclusionRadical excision of skull base giant cell tumor may be hazardous but if achieved is the optimal treatment and may be curative.

We present a GCT of the temporal bone in a 26 year old male which was treated with radical surgery with a good outcome
Summary
Giant cell tumor (GCT) of bone is an uncommon primary bone neoplasm that usually occurs in the long bones It is rarely encountered in the skull where it is preferentially seen to involve the sphenoid and the temporal bones. CT scan of the brain showed a large well defined hyperdense contrast enhancing lesion originating from the right temporal bone – squamous and petrous portions with a large intracranial extension causing uncal herniation [Fig. 1 &2]. Preoperative axial CT scan which shows a large hyperdense tumor arising from the petrous portion of the right temporal bone with intracranial extension and impending uncal herniation. The tumor was firm, reddish brown and vascular It had destroyed the squamous temporal bone, lateral petrous portion, zygomatic arch and was seen invading the cranium pushing the temporal bone superiorly and medially along with the dura [Fig. 3]. Follow up CT at 6 months and 12 months did not reveal any recurrence
