A series of 14 cases of circumscribed nontraumatic myositis ossificans is presented. It is important to recognize the clinical and radiographic findings of this benign entity whose appearance, especially early on, simulates a neoplasm. The natural history and therapeutic indications are also described.

A ten year nine month-old girl was admitted to hospital for a painful inflammatory tumour of the right popliteal area. There was a calcification on X-ray and computerised angiography showed a tumour. MRI showed a heterogenous irregular mass. This looked like a malignant tumour. At surgical biopsy: it was a circonscripta myositis ossificans. This benign tumour of soft tissues, rare in children (25 cases in the literature), had a spontaneous favourable evolution. Differential diagnosis with malignant tumour is well known, but is still difficult. Biopsy is necessary in doubtful cases. We had to remove the mass because of acute pain.

An eleven year old boy presented with localized swelling of the left calf which had been developing for more than 5 years. Another smaller mass was found in the pretibial area. There was an invincible equinus deformity of the foot. Surgical biopsies revealed characteristic histological features of focal myositis showing necrotic and regenerating muscle fibers, randomly distributed, with inflammatory infiltration. An intense fibrotic reaction was observed. This constitutes to our knowledge the first reported case of focal myositis in which development of muscle sclerosis was so important that it was necessary to perform tenotomies one year after excision of the principal tumor in order to restore normal gait. A nearly two-years follow-up does not give evidence of recurrent lesion.

A case of traumatic myositis ossificans of the iliopsoas muscle in a 13 year old ballet dancer is presented. A history of multiple minor injuries to the region of the left hip in addition to the radiographic appearance of calcification were indicative of ectopic bone formation. The lesion was explored surgically because of the clinical symptoms of the coexistant femoral hernia as well as to obtain biopsy material to exclude a soft tissue tumor. Histological examination demonstrated the zoning effect of myositis ossificans with patterns varying from a cellular central zone to a peripheral one of fairly well oriented bone. The patient remains symptom-free and no radiographic evidence of recurrence was observed four years postoperatively.

The authors report one case of a bilateral atraumatic circumscribed myositis ossificans (C.M.O.) developed from the triceps muscles with major equinism, in a 15 years old girl. One side presented a current tumor, the other was seen at the first episode. The authors obtained a good functional result after surgical treatment and advocate this treatment.
