title: Haemangiopericytoma: problems in diagnosis and management.
abstract: Three cases of haemangiopericytoma with diverse modes of presentation are reported. The difficulties with clinical diagnosis are emphasized. There is no consensus on the best mode of treatment, and we have chosen radical surgical excision in the first instance, but have not hesitated to employ radiotherapy or chemotherapy as adjunctive treatment if the need has arisen. The clinical behaviour of this tumour is unpredictable; therefore the prognosis for life must remain uncertain.
