title: Chronic subdural hematoma after transsphenoidal surgery.
abstract: Chronic subdural haematoma has not been reported as a complication of transsphenoidal surgery. We present a case of pituitary adenoma which was gross-totally removed by transsphenoidal surgery with the enlarged sellar opening. Postoperative serial imaging showed massive air accumulation in both frontal subdural spaces followed by subdural fluid collection and subsequent chronic subdural haematomas 2 months later. We conclude that close follow up imaging study is required to avoid overlooking chronic subdural haematoma when massive air is introduced into the subdural space by the transsphenoidal surgery.
