Isolated Sphenoid Sinusitis with Orbital and Intracranial Complication

ABSTRACT

Sphenoid sinus is adjacent to important intracranial structures, such as major intracranial vessels and some cranial nerves. However isolated sphenoid sinusitis is often misdiagnosed because presenting symptoms are initially subtle. Therefore, if the diagnosis of the isolated sphenoid sinusitis is delayed and complications occur, it will lead to disastrous results. We experienced a rare case in which a 51-year-old male patient developed both brain abscess and abuducens nerve palsy and report this case with a review of the case and related articles.
