A suprasellar Aerocele as a Complication of Endoscopic Transsphenoidal Surgery: A Case Report.

CSF leak-related pneumocephalus is a rare complication of endoscopic transsphenoidal surgery (ETSS) and has been reported in previous studies. We are presenting a rare case of subdural pneumocephalus, unassociated with CSF leak, that developed in the sellar and suprasellar regions. This complication was diagnosed in an adult male 1 week after the removal of a large tumor in the same site via ETSS.
