Pituitary apoplexy is characterized by sudden increase in pituitary gland volume secondary to ischemia and/or necrosis, usually in a pituitary adenoma. Most cases occur during the 5th decade of life, predominantly in males and in previously unknown clinically non-functioning pituitary adenomas. There are some predisposing factors as arterial hypertension, anticoagulant therapy and major surgery...

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...

Hypopituitarism is defined as deficiency of all anterior pituitary hormone1. Panhypopituitarism when there both and posterior hormone. In this case report our 50 year old male diagnosed with apoplexy (bleeding in rathke’s pouch) started on intravenous steroids later oral he improving clinically.

BACKGROUND It is rare for patients with pituitary apoplexy to exhibit concomitant subarachnoid hemorrhage (SAH). Only a handful of patients with pituitary apoplexy have developed such hemorrhagic complications, and histopathological examination revealed pituitary adenoma as the cause of SAH. CASE REPORT A previously healthy 35-year-old woman was brought to our institution after complaining of...

Brain and optic chiasm herniation has been rarely reported following dopamine agonist treatment for large prolactinomas. We report a case of brain and optical chiasm herniation, secondary to an empty sella due to apoplexy of a prolactinoma, and we focus on the specific presentation of this case. A 32-year-old female presented to a neurologist complaining of headaches. Her past medical history w...
