“…As long as I surveyed, only 3 cases of myositis ossificans in lumbar spine were found on PubMed line. [2][3][4] Interestingly, all of the 3 cases had no traumatic history like our case. It could be because the muscle contusion by playing sports might be rarer in the spine than in the extremities.…”

Objective: Relatively rare case. Background: Myositis ossificans is a benign condition which appears as a heterotopic, welldefined bone formation in muscles and soft tissues. It is most common in children and young athletes. Most myositis ossificans occur in the large muscles of proximal extremities such as the quadriceps and brachialis and it is rare to occur in the lumber spine. Case Report: We present a case of a 12 year-old Japanese boy with severe lower back pain. On physical examination, a severe tenderness and swelling was present in the left lumbar region, at level of L4/5. He had a traumatic history of his back. He hit nunchak (one of tools of Chinese martial arts) on the back when he was practicing it at school three months ago. Both lumbar radiograph and lumbar Computed Tomography (CT) examination showed a ring like osteoblastic lesion calcification around left facet joint of L4/5 suggestive of myositis ossificans. He received conservative treatment. His back pain and swelling disappeared in 2 months. Follow up lumbar CT examination 8 months later showed the osteoblastic lesion calcification was more prominent than the one in the previous CT. Soft tissue swelling around the osteoblastic calcific area was not detected. Conclusion: This case was unusual location for myositis ossificans. Careful correlation of the clinical and radiological findings is necessary to avoid surgical treatment.

“…As the lesion matures, cancellous bone develops into mature, lamellar bone in the periphery of the lesion. 3 In addition, repetitive minor mechanical injuries, ischemia or inflammation have been implicated as possible causative factors.…”

“…La miositis osificante es un proceso osificante heterotópico, benigno y autolimitado, que afecta predominantemente a los músculos de las extremidades en el 80% de los casos, (1) siendo más frecuente en sitios de alto riesgo de traumatismo como muslos, glúteos y codos. (1,6) Sólo unos pocos casos de miositis osificante no traumática han sido descritos en la musculatura paravertebral lumbosacra. (6) La miositis osificante puede ocurrir a cualquier edad, pero la mayor incidencia se presenta en la segunda y tercera décadas de la vida; y en cuanto a su etiología, la historia de traumatismo previo aparece en el 60-75 % de los pacientes.…”

ResumenLa miositis osificante es una osificación heterotópica, autolimitada, que afecta a cualquier grupo de edad y suele presentarse en la musculatura de las extremidades, en su variante más frecuente, en zonas de traumatismo por su relación íntima con la lesión mecánica.Es considerada benigna y si la identificación por imágenes es clara, su tratamiento consiste en seguimiento clínico. Sin embargo, cuando existen dudas diagnósticas, conviene realizar biopsia para definir el tratamiento quirúrgico.Presentamos una paciente con tumoración dolorosa en región lumbar, a nivel del triángulo de Petit, de 18 meses de evolución. La biopsia de partes blandas era sugerente de tumor fibromixoide osificante cuyo análisis postoperatorio reveló miositis osificante.Se realizó extirpación local amplia y reconstrucción con malla biológica sin tensión y cierre por planos, ya que se han descrito hernias espontáneas y también secundarias a través del triángulo de Petit. Estas últimas, en su mayoría, son hernias postincisionales.

Soft tissue lesions are commonly encountered and imaging is an important diagnostic step in the diagnosis and management of these lesions. While some of these lesions are true neoplasms, others are not. These soft tissue tumor mimickers can be due to a variety of conditions including traumatic, iatrogenic, inflammatory/reactive, infection, vascular, and variant anatomy. It is important for the radiologist and clinician to be aware of these common soft tissue tumor mimickers and their characteristic imaging features to avoid unnecessary workup and provide the best treatment outcome.
