[Multiple extracranial metastases from a meningeal hemangiopericytoma and severe hypoglycemia: a case report].

Extracranial multiple metastases from meningeal hemangiopericytoma have been reported only rarely. The authors describe the case of a 61-year-old woman, who was previously diagnosed as having primary meningeal hemangiopericytoma with its multiple metastases to the liver, lumbar spine, etc. and who suffered from a sudden attack of hypoglycemia. Considering the history of her present illness, this hypoglycemic shock was most likely brought on by the remarkable metastatic tumors to the liver. Recent literature pertinent to hypoglycemia suggests that insulin-like growth factor-II (IGF-II) produced by tumor is strongly suspected to be involved in the development of hypoglycemia.
