Growth hormone (GH)-producing PitNET/pituitary adenoma (suspected to be a densely granulated tumor). A 51-year-old female, whose shoe size and ring no longer fit. The GH level is at 13.9 ng/mL and the IGF-1 level is at 589 ng/mL. a Coronal T2WI shows hypointensity mass (arrow). b Coronal contrast-enhanced T1WI shows a hypointensity mass (arrow). The patient underwent surgery via the transiliac sinus approach. Pathologically, the patient was diagnosed as a GH-producing pituitary PitNET/pituitary adenoma. No medical treatment was administered. GH and IGF-1 levels subsequently normalized
