Pituitary function after pituitary apoplexy.
Pituitary function was studied in nine patients who had recovered from pituitary apoplexy. All the patients recovered spontaneously; none required immediate surgery. Four of the patients had acromegaly, two had pituitary-dependent Cushing's syndrome, and a "functionless" pituitary adenoma was found in three. Low serum growth hormone concentrations were observed in three patients with acromegaly whereas the concentration remained increased in the fourth one. Of the two patients with Cushing's syndrome, a selective ACTH-deficiency developed in one and Nelson's syndrome appeared with excessive secretion of ACTH in the other. Transient or persistent hypofunction of the anterior pituitary occurred in al patients. Three patients underwent hypophysectomy after respective intervals of three, eight and 12 months after pituitary apoplex. The operation revealed a hemorrhage in one functionless adenoma and a large cyst in another one. In the third patient who had acromegaly, no signs of the pituitary apoplexy were observed at operation.
