Pituitary Gland Apoplexy

Definition 1

A rare, potentially life-threatening disorder caused by acute ischemic infarction or hemorrhage in the pituitary gland. It is most often associated with the presence of a pituitary gland adenoma. Signs and symptoms include headache, vomiting, visual disturbances, and endocrine dysfunction. (NCI Thesaurus)

Definition 2

Sudden hemorrhage or ischemic necrosis involving the pituitary gland which may be associated with acute visual loss, severe headache, meningeal signs, cranial nerve palsies, panhypopituitarism, and rarely COMA. The most common cause is hemorrhage (INTRACRANIAL HEMORRHAGES) related to a pituitary ADENOMA (see also PITUITARY NEOPLASMS). Ischemia; MENINGITIS; INTRACRANIAL HYPERTENSION; and other disorders may be associated with this condition. (NLM, Medical Subject Headings)
