Congenital mastoid cholesteatoma of adult patient masquerading as complicated otitis media – A case report and literature review

The study highlights the management protocol of a large mastoid cholesteatoma presenting with sudden-onset facial palsy mimicking a complicated otitis media and literature review. Congenital cholesteatoma may affect various regions of the temporal bone, the mastoid process being the least frequently involved. The diagnosis is often missed, specifically when the patient presents with features of mastoiditis. Radiology plays an important role in clenching the diagnosis. Congenital (mastoid) cholesteatoma manifesting with features of complicated otitis media is a rare occurrence and needs familiarity to facilitate early diagnosis and appropriate management.
