A case of pituitary apoplexy with spontaneous recovery

A patient, 38-year-old man, with hemorrhage into a prolactin-secreting pituitary adenoma, or pituitary apoplexy, is reported. On his admission, clinical examinations revealed typical stigmata indicating that he suffered from an acute attack of pituitary apoplexy probably induced by acute meningitis. He survived the acute attack and recovered spontaneously without an urgent operation. Although there was no suspicious sign and symptom of hypopituitarism, the first study performed immediately after the attack suggested strongly that hypopituitarism might acutely developed during the hemorrhage into the tumor. Moreover, the follow-up studies indicated that TSH, LH and ADH recovered spontaneously from the initial damage following the resorption of hemorrhage for the next 3 months.
