Apoplexy of Pituitary Macroadenoma after Combined Test of Anterior Pituitary Function.

Pituitary apoplexy after combined test of anterior pituitary function.

Pituitary apoplexy after thyrotropin-releasing hormone stimulation test in a patient with pituitary macroadenoma.

Pituitary apoplexy is a rare complication of pituitary tumors. We report a case of a 41-year-old female with acromegaly due to a pituitary macroadenoma, who developed pituitary apoplexy after a thyrotropin-releasing hormone (TRH) 200 microgram intravenous injection stimulation test. Neither emergency computed tomography (CT) scans nor magnetic resonance imaging (MRI), performed 6 hours and 12 h...

Development 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...

Delayed 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 ...

Combined test of anterior pituitary function in children.

A combined test of anterior pituitary function was used on 21 normal children. It shows that a comprehensive evaluation can be made of growth hormone, thyroid stimulating hormone, adrenocorticotrophic hormone, and gonadotrophin reserve. Simultaneous assessment of those peripheral glands associated with the anterior pituitary is possible by the measurement of thyroid hormones, cortisol, and gona...
