title: [Malignant spinal hemangiopericytoma, with benign radiological appearance].
abstract: A spinal intra-dural and extra-medullary tumour is described, presenting both clinically and radiologically as a benign process. However, the pathological examination, helped by electron microscopy, concluded in favour of a malignant hemangiopericytoma. The clinical cause, after surgery and radiotherapy, confirmed this latter diagnosis.
