title: [Successful therapy of recurrent hypoglycemias by surgical removal of a malignant hemangiopericytoma].
abstract: Tumor growth in a 72-year-old male patient with malignant haemangiopericytoma in the left hemithorax could be followed radiologically for 4 years before symptoms of recurrent hypoglycaemia appeared. The endogenous insulin level in serum was maximally and serum IGF-1 and IGF-2 markedly reduced. An intravenous arginine load test showed a normal stimulation capacity of the pancreatic glucagon secretion but not that of insulin. After resection of the tumor, blood sugar metabolism was completely normalised. The insulin level, IGF-1 and IGF-2 in serum returned to normal.
