title: Hemangiopericytoma-associated hypoglycemia improved by glucocorticoid therapy: a case report.
abstract: A 59-year-old man was admitted because of recurrent, severe hypoglycemia. He had multiple metastases from a meningeal hemangiopericytoma, which had been operated on 12 years earlier. The results of laboratory testing at the time of hypoglycemia showed very low serum levels of insulin, C-peptide, and growth hormone, with slightly high levels of insulin-like growth factor-II, and a normal level of insulin-like growth factor-I. The diagnosis of hemangiopericytoma-associated hypoglycemia was proposed. The patient was given corticosteroid therapy, which ameliorated symptoms of hypoglycemia.
