We present an unusual complication of acromegaly: a 22 year old woman with amenorrhea (6 month ago) and blurred vision of left eye (4 month ago) referred to Ghaem neurology clinic in Mashhad. With a growth hormone (GH) level of =100ng/ml, Insulin like growth factor-1 (IGF-1) =1560 ng/ml and pituitary macro adenoma in magnetic resonance imaging (MRI), she was candidated for surgery. A few hours before surgery she had dyspnea, loss of consciousness, fever and with blood sugar (BS) =500 mg/ml, Hco3=2.4, PH=7.06 and keton in urine. Diabetic ketoacidosis was diagnosed.
