Large giant cell tumor of the temporal bone presenting as mild conductive hearing loss

Abstract

Introduction: Giant cell tumor of bone or osteoclastoma is a relatively rare primary neoplasm of temporal bone. It usually involves the epiphyseal region of long bones. Primary involvement of bones of the skull appears to be uncommon. Case report: we report a case of giant cell tumor of temporal bone arising in a 33 years old man. The presenting symptom is only mild conductive hearing loss. A computed tomography (CT) scan showed a large well circumscribed mass within the right temporal bone, the posterior cranial fossa and the infratemporal fossa. Biopsy and subsequent resection showed a giant cell tumor of bone. Conclusion: Temporal bone tumor may be presented with symptoms such as mild hearing loss or aural fullness. So we always must be attention rare reasons of common symptoms.
