Hemangiopericytoma. Apropos of a case in the thoracic muscles. Contribution of imaging technics (excluding MRI). Review of the literature

: The authors describe a recurrent case of an hemangiopericytoma of the left serratus anterior muscle, touching a 21 year-old woman. The different ways of imaging are exposed and compared with data of literature. It seems that none of them offers any decisive possibility of nature diagnosis. Conversely, radiological examinations are of greatest interest in the initial lesional statement, in the follow up and in early discovery of a possible recurrence, principally in case of difficulties in the pathological examination. CT appears to have the first role among the different ways of medical imaging, initially and in the appreciation of clinical course.
