Osteoma of temporal bone is a rare benign neoplasm commonly arising from mastoid bone. Rarely, it may arise from petrous bone in cerebellopontine angle producing sensorineural hearing loss. This article describes computed tomography scan (CT scan) and magnetic resonance imaging (MRI) findings in a rare case of petrous bone osteoid osteoma producing ipsilateral sensorineural deafness.
