Abstract
This report deals with a detailed course of one patient with acromegaly who had a pituitary apoplexy. The pituitary apoplexy occurred suddenly 5 days after administration of a oral hypoglycemic agent, buformin, during hospitalization. Immediately after the attack changes of the concentrations of several hormones such as serum growth-hormone, serum thyroid hormone and urinary 17-hydroxycorticoids were followed until the development to hypopituitary state. Simultaneously with the decrease of the concentrations of the above-mentioned hormones, a regression of the physical manifestations of acromegaly and a complete amelioration of diabeteszmellitus were observed.
