Non-classical presentation of congenital cholesteatoma as cerebrospinal fluid rhinorrhea - Case report and systematic review of the literature

The diagnosis of otogenic cerebrospinal fluid (CSF) rhinorrhea is challenging and it can easily be misdiagnosed. Congenital cholesteatoma is a rare entity. We present a non-classical presentation of CC in an adult male, with a previously unreported symptom of CSF rhinorrhea. Symptomatic improvement occurred after surgical treatment of the disease.
