GIANT-CELL TUMOR OF THE TEMPORAL BONE PRESENTING AS VERTIGO

We report a case of giant cell tumour of the temporal bone arising in a 31-year-old man. The presenting symptoms were unusual, being rotatio nal vertigo, unilateral tinnitus, and hearing loss. A computed tomogra phy (CT) scan showed a large mass within the right temporal bone and t he infratemporal fossa. The radiological appearance was suggestive of an aggressive primary neoplasm arising within bone. Biopsy and subsequ ent resection showed a giant cell tumour of bone. The tumour was histo logical grade 1. At two-year follow-up, there was no evidence of tumou r recurrence or metastasis.
