Pneumocephalus as a Complication of Transsphenoidal Surgery for Pituitary Adenoma: A Case Report.

Pneumocephalus (PNC) is a rare complication of transsphenoidal surgery that can result from cerebrospinal fluid (CSF) leak, allowing air entry into the CSF. We report the case of a 49-year-old female patient who presented to the emergency department three weeks after a transsphenoidal pituitary tumor resection, with symptoms of generalized throbbing headache associated with nausea. The patient was alert and oriented without any focal neurological deficit.
