title: Recurrent intracranial haemangiopericytoma compatible to synovial sarcoma.
abstract: A rare case of intracranial haemangiopericytoma with a thrice recurrence, treated by gross total removal and local irradiation is presented. Histological examination of the tumour specimen showed haemangiopericytoma (WHO grading III). The tumour has not recurred for 15 months after third operation and 30 sessions of radiotherapy, although the effectiveness of radiation for haemangiopericytoma is unclear.
