Abstract:
Giant cell tumours (GCTs) of the cranium preferentially affect the sphenoid and temporal bones. We report a 19-year-old patient with GCT involving the left occipital bone and petromastoid portion of the temporal bone. CT and MRI revealed a predominantly expansive soft-tissue mass of the posterior cranial fossa. The patient underwent surgery. Permanent histopathological sections and immunostatins revealed the presence of a GCT. The radiological features and method of surgical intervention of this rare lesion are discussed.
