Pneumocephalus as a Complication of Transsphenoidal Surgery for Pituitary Adenoma: A Case Report.
Curēus 2018 August 6
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. A head computed tomography (CT) scan showed air in the subarachnoid space and ventricles. She was admitted to the hospital and was initially treated conservatively. However, her symptoms persisted, and a repeat head CT scan demonstrated worsening PNC. She then underwent lumbar drain placement and sellar floor repair. Her symptoms resolved postoperatively. When PNC results in intracranial hypertension, it is referred to as tension PNC, a complication that can be fatal. Conservative treatment involves analgesics and therapy for intracranial hypertension. Surgical intervention to decrease intracranial hypertension and repair the CSF leakage may also be necessary.
