Headache after transphenoidal surgery for intrasellar mass with hemorrhage. There are postoperative findings related to recent transsphenoidal surgery. There is a small amount of fluid signal along the inferior aspect of the pituitary, measuring up to 3 mm in thickness, which corresponds to the site of the decompressed cystic lesion. There is also heterogeneous material within the sphenoid sinuses, which may represent at least in part blood products. Otherwise, the remaining pituitary gland is not enlarged and the infundibulum is intact. There is no mass effect upon the cavernous sinuses or optic apparatus. There is a subcentimeter focus of heterotopic grey matter along the lateral aspect of the right lateral ventricle.
