Miositis osificante traumática: a propósito de un caso

Abstract

Traumatic myositis ossificans is a rare pathology of uncertain etiology although it is now accepted that it is by metaplasia of connective tissue. It usually affects adolescents and young adults, usually as a result of trauma on a muscular area, 80% in the lower extremities. Symptoms appear two or three weeks after although most patients do not remember the trauma. Radiography, ultrasonography, computed tomography or magnetic resonance may be required for diagnosis, which sometimes, cannot distinguish from malignant lesions such as soft tissue sarcomas or osteosarcomas. Therefore, definitive diagnosis often requires biopsy. Treatment is usually conservative. Surgery is performed only in selected cases for the risk of recurrence.
