[Associated vertebral angioma and epidural cavernoma (author's transl)].

A 27 year old man developed a pyramidal syndrome with hypoesthesia up to the level of D8, over a period of two months. Radiographic examination revealed the presence of an angioma of D8. Selective angiography demonstrated that there was epidural invasion as well as an angioma of the vertebral body, and enabled embolization of the 2 pedicles of the lesion to be performed. This produced only a partial, temporary improvement, and a posterior epidural tumor was found and removed by operation. The histological appearance of the tumor was that of a cavernoma, and rapid and permanent recovery of normal neurological function was obtained after the operation. The authors discuss the pathogenicity of the neurological disorders associated with single bone angiomas, and the problems raised by their treatment.
