Pituitary adenomas may be manifested with visual field defects or rarely in the form of total oculomotor palsy. Visual field defect is most frequently in the form of bitemporal hemianopsia and superior tempo...
متن کاملDevelopment of pituitary apoplexy during TRH/GnRH test in a patient with pituitary macroadenoma.
Pituitary apoplexy occurs as a very rare complication following pituitary function tests. Signs and symptoms are due to the rapid expansion of an infarcted and/or haemorrhagic pituitary adenoma. We report a case of macroadenoma, in which pituitary apoplexy developed 30 minutes after administration of thyrotropin-releasing hormone (TRH) and gonadotropin-releasing hormone (GnRH) injections. Magne...
متن کاملDelayed postoperative pituitary apoplexy after endoscopic transsphenoidal resection of a giant pituitary macroadenoma.
Postoperative pituitary apoplexy is rare and usually occurs in the immediate postoperative period (within 12 hours) after subtotal resection of giant pituitary macroadenomas with fatal outcomes. We describe a unique patient with pituitary apoplexy occurring in a delayed fashion on the third postoperative day. Early detection and emergent endoscopic transsphenoidal exploration resulted in gross ...
