Intrasphenoidal meningoencephalocele: a case report

A case of intrasphenoidal meningoencephalocele is presented, representing the eighth case report in English language literature. The major presenting symptom was retro-orbital headache. The patient also had cerebrospinal fluid rhinorrhea and a history of recurrent meningitis. Diagnosis was suspected on the basis of plain radiographs of the sinuses and was confirmed by computed tomography scan. The meningoencephalocele was reduced via a sublabial, transseptal sphenoidotomy approach with improvement of the patient's symptoms. Management and treatment of isolated sphenoid sinus lesions are discussed as well as the pathophysiology of intrasphenoidal meningoencephaloceles.
