Rare case of mastoid osteoma: a case report





Osteoma, Temporal bone, Mastoid


Osteoma of the temporal bone is a very rare slow growing benign tumour of bone. They commonly arise from skull. Temporal bone osteomas are commonly present without symptoms, but may cause bony deformity, pain, and hearing loss depending upon the site. Osteomas may arise from external ear canals, but very rarely from mastoid bone. Aetiology is unknown and many theories are postulated like congenital, traumatic and infectious. Here, we are presenting a case of 30 years old lady, presenting with progressively enlarging hard lump behind right ear for 3 years. It was diagnosed as osteoma and confirmed by computed tomography (CT) scan. Complete excision is done until normal mastoid cortex/air cells are exposed.
