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

ABSTRACT

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. 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. 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
