A 48-year-old woman with a known history of metastatic haemangiopericytoma presented with intractable hypoglycaemia. Hypoglycaemia was accompanied by undetectable serum insulin levels with high levels of proforms of insulin-like growth factor-II ('big' IGF-II). Reduction of tumour load with embolisation resulted in a normal pattern of serum glucose levels throughout the day.
