title: A boy with normal growth in spite of growth hormone deficiency after resection of a suprasellar teratoma.
abstract: We reported a boy with panhypopituitarism after removal of a suprasellar teratoma and pituitary stalk transection at the age of 3 months. His growth was accelerated after 5 years of age without growth hormone (GH) therapy, although he had poor height growth until age 4 under treatment with hydrocortisone, levothyroxine sodium, and desamino-D-arginine vasopressin (DDAVP). Hyperphagia and obesity developed after surgery. Endocrinological examination revealed no GH response to glucagon, low serum levels of insulin-like growth factor (IGF)-1 and IGF binding protein-3 (IGFBP-3). Serum prolactin was normal, but serum insulin was high. Some patients who received an operation for craniopharyngioma were reported to achieve normal growth without GH secretion, but the mechanism is still unknown. High serum levels of prolactin or insulin can be associated with normal IGF in GH deficient patients. This patient had obesity and high serum insulin, which may be related to growth without GH secretion.
