Spontaneous sphenoid sinus meningocele with associated amenorrhea and headache: illustrative case.

Abstract

Developmental meningoceles of the sphenoid sinus are uncommon. When encountered, they are often associated with cerebrospinal fluid (CSF) rhinorrhea. The authors present the case of a 27-year-old female with a large meningocele eroding through the sella turcica and sphenoid sinus into the nasopharynx. The patient presented with intractable headaches and amenorrhea without CSF rhinorrhea. The patient underwent an endoscopic endonasal transsphenoidal reduction of the meningocele with reelevation of the pituitary gland and skull base reconstruction with abdominal fat graft and nasoseptal flap.
