## Abstract

Mastoid osteoma is a benign osteoblastic tumour with a low incidence and has rarely been documented in childhood and adolescence. It
manifests as a solitary lesion and the size rarely exceeds 3 cm at the time of presentation. The diagnosis is based on clinical and
radiological findings. Complete excision of the tumour is the recommended treatment, based on the cosmetic concerns. We report a case of
a giant mastoid osteoma in an 11-year-old female and outline its presentation, diagnosis and management.
