Mastoid Mucocele with Intracranial Complication Presenting as Acute Otomastoiditis

Abstract Mucocele is a benign epithelial-lined mucoid-filled sac that may sound harmless but has the potential of expanding at the expense of its surrounding bony architecture. The incidence of its emergence from the mastoid bone is relatively rare, whereas one that results in intracranial complications is almost unheard of. We present the case of a patient presenting with the symptoms of a middle ear infection, which was initially treated as refractory acute otitis media with intracranial complication. However, intraoperative findings revealed an infected mucocele within the mastoid bone.
