Epidural abscess associated with dural sinus thrombosis due to intracranial extension of cholesteatoma

ABSTRACT

Cholesteatoma of the temporal bone extending into the intracranial region is an unusual occurrence. Acquired aural cholesteatoma can extend into either the middle or posterior cranial fosses. Epidural abscess and dural sinus thrombosis are complications of chronic otitis media with cholesteatoma, although potentially fatal, they are treatable. Epidural abscess and dural sinus thrombosis must be recognized and treated aggressively. Epidural abscess and dural sinus thrombosis is relatively more common [14], and treatment of the underlying cause is essential. In this study cholesteatoma extended into the posterior fossa, associated with epidural abscess and lateral sinus thrombosis. While computed tomography and magnetic resonance imaging are both required to differentiate temporal bone cholesteatoma from other lesions of the temporal bone [14], computed tomography of the temporal bone is usually sufficient to diagnosis and define intracranial extension of acquired aural cholesteatoma. The present study is presented to analyze the clinical presentation, imaging finding, and surgical treatment of patients with acquired aural cholesteatoma extending into the intracranial region associated with epidural abscess and lateral sinus thrombosis
