Pituitary apoplexy often occurs spontaneously in adenomas. A few cases have been reported after testing anterior pituitary function by means of intravenous injections of a mixture of gonadotropin-releasing hormone and thyrotropin-releasing hormone, or gonadotropin-releasing hormone alone. In these cases the development of visual field defects has necessitated surgical intervention, which confirmed pituitary apoplexy. We describe a patient with a pituitary macroadenoma. He developed symptoms and signs of pituitary apoplexy immediately after intravenous injection of a mixture of hypothalamic releasing hormones. His visual fields remained normal, and he recovered spontaneously.

UI MeSH Term Description Entries
D007275 Injections, Intravenous Injections made into a vein for therapeutic or experimental purposes. Intravenous Injections,Injection, Intravenous,Intravenous Injection
D007987 Gonadotropin-Releasing Hormone A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE. GnRH is produced by neurons in the septum PREOPTIC AREA of the HYPOTHALAMUS and released into the pituitary portal blood, leading to stimulation of GONADOTROPHS in the ANTERIOR PITUITARY GLAND.

D008297 Male Males
D010899 Pituitary Apoplexy The sudden loss of blood supply to the PITUITARY GLAND, leading to tissue NECROSIS and loss of function (PANHYPOPITUITARISM). The most common cause is hemorrhage or INFARCTION of a PITUITARY ADENOMA. It can also result from acute hemorrhage into SELLA TURCICA due to HEAD TRAUMA; INTRACRANIAL HYPERTENSION; or other acute effects of central nervous system hemorrhage. Clinical signs include severe HEADACHE; HYPOTENSION; bilateral visual disturbances; UNCONSCIOUSNESS; and COMA. Apoplexy, Pituitary

D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D013973 Thyrotropin-Releasing Hormone A tripeptide that stimulates the release of THYROTROPIN and PROLACTIN. It is synthesized by the neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, TRH (was called TRF) stimulates the release of TSH and PRL from the ANTERIOR PITUITARY GLAND.
