Cerebral haemangiopericytoma treated with conservative surgery and radiotherapy.

Cerebral haemangiopericytomas are rare tumours that resemble meningiomas but behave more aggressively, with a tendency to metastasize. We report two patients with haemangiopericytoma who had limited surgical resections owing to perioperative blood loss but who had massive tumour shrinkage after a course of radical radiotherapy. We suggest a more conservative surgical approach to the management of these tumours.
