[Myositis ossificans circumscripta: a case report]. / La myosite ossifiante circonscrite: à propos d'un cas.

Myositis ossificans circumscripta is a benign lesion characterized by focal heterotopic soft tissue ossification, occurring in young people generally after localized trauma. Clinical and radiological appearances may mimic a sarcomatous neoplastic process. We report a case of myositis ossificans occurring after trauma, so as to illustrate the different imaging features of this benign pathology on conventional radiographs and computed tomography.
