Intraabdominal haemangiopericytoma associated with uncontrolled diabetes mellitus

Haemangiopericytoma (HPC) is a rare tumour with a predilection for the central nervous system. Though previously thought to originate from the meninges and ventricular walls, HPC's are currently accepted as distinct mesenchymal neoplasms unrelated to meningiomas. Haemangiopericytomas have been previously reported to be associated with the production of insulin like growth factor II (IGF-II) and hypoglycaemia. A case of a 61-year-old poorly controlled diabetic lady with a rare presentation of an abdominal haemangiopericytoma is discussed. A laparoscopic assisted resection of the massive lobulated tumour arising from the parietal peritoneum with dense attachment to the diaphragm and the liver was performed with an uncomplicated postoperative recovery. Control of the patient's diabetes improved dramatically following surgery and the rare association of hyperglycaemia and HPC, which has not been previously described, is elaborated upon in this report.
