Abstract
External auditory canal (EAC) osteoma is a slow-growing benign tumor. It appears as a single, pedunculated hyperdense lesion. Most osteomas are asymptomatic and treated conservatively while surgery is reserved for symptomatic osteomas. Surgical excision of EAC osteoma is approached either endoscopically or microscopically by postauricular, endaural, or transcanal approaches depending on the site and size of osteomas. We report a case of external auditory osteoma presented with an atypical finding of multilobulated mass with peripheral calcification on computed tomography scan.
