Pituitary Apoplexy:
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.
