A CASE OF MENINGEAL HEMANGIOPERICYTOMA WITH POSTOPERATIVE METASTASIS TO THE ABDOMINAL CAVITY AND LUMBAR REGION CAUSING HYPOGLYCEMIA

Abstract

Second Department of Surgery, Kinki University School of Medicine A 57-year-old woman was admitted to the hospital because of hypoglycemia. There was a previous history of undergoing a removal of a tumor in the occipital lobe 12 years before admission, which was histologically diagnosed as angioblastic meningioma. The fasting blood sugar level was 30 mg/ml, and both levels of immunoreactive insulin and C-peptide were low. Abdominal ultrasonography, CT scan, magnetic resonance imaging, and arteriography revealed multiple localized tumors in the abdominal cavity and lumbar region. The histological findings of the resected tumor in the lumbar region were compatible with those of hemangiopericytoma and identical to those of the previous brain tumor. Thus, the multiple tumors were diagnosed as metastasis of meningeal hemangiopericytoma. We considered that curative resection was impossible. Arterial embolization for the two large tumors aiming at improving hypoglycemia was successful.
