title: [Intraspinal hemangiopericytoma. 2 cases and review of the literature].
abstract: Two cases of intraspinal meningeal hemangiopericytomas are reported, one of which cervical and the other one dorsal with relapse. The anatomopathological features of the hemangiopericytomas are recorded and the nosological problems of their meningeal localizations are discussed. As in the case of intracranial meningeal hemangiopericytomas, the clinical, radiological and macroscopic features of intraspinal hemangiopericytomas--to the exception of a few particular cases--resemble those of other localizations of these tumours more than those of meningiomas, in the light of the review of twenty-eight cases to be found in the relevant literature. Treatment of such tumours hasn't as yet been well circumscribed. Surgical treatment may be facilitated by preoperative embolization. Radiotherapy must be associated to it, at least when removal is incomplete, because of frequent recurrence.
