title: Hepatic metastasis from a meningeal haemangiopericytoma.
abstract: Intracranial tumours rarely metastasize outside the central nervous system (CNS). Meningeal haemangiopericytoma is an exception. We report the case of a 41-year-old female who initially presented in 1984 with what was thought to be a posterior fossa meningioma which was excised, as were two subsequent recurrences in 1987 and 1988. In October 1990 she represented, having discovered a mass in her abdomen. This proved to be a metastatic haemangiopericytoma in the liver which had similar histology to the original intracranial tumour. This metastasis, and another found at operation, have been excised, and at the time of this report, she is alive and well seven months after surgery without any evidence of other metastasis or recurrence. Hemangiopericytomas are unusual in their propensity to metastasize outside the CNS and successful resection of hepatic metastases from this tumour has not been reported before.
