“…In myositis ossificans, a specific form of heterotopic ossification, the imaging appearance reflects the stage of maturation of the lesion. A soft tissue mass with circumscribed or peripheral calcification and a relative lucent center typically is seen on radiographs in the subacute phase, whereas the chronic phase often reveals a more densely ossified mass with a cortex surrounding central trabecular bone [1,10], unlike the small uniform ossifications observed in this case. Synovial chondromatosis is an uncommon benign condition, which involves the synovial lining of joints, tendon sheaths, or bursae [8,9].…”

A 32-year-old woman presented with onset of progressive left leg pain and swelling after minor trauma 8 weeks previously. Approximately 6 weeks after injury, she was evaluated by a physician at an outside hospital and was prescribed crutches. Imaging studies at that time revealed a calf mass. She then was referred to our orthopaedic clinic for further evaluation. The pain was aggravated by walking, prolonged sitting, or standing. On physical examination, her left calf was tender to palpation and asymmetrically enlarged relative to the contralateral side. A calf mass was palpated. The mass extended from the proximal popliteal fossa down to the lower distal third of the tibia, clinically measured approximately 18 cm, was firm throughout its length, not freely movable from the tibia, and appeared to be deep to the subcutaneous tissue. Radiographic and MR evaluations of the patient's left calf were performed. Based on the history, physical examination, and imaging studies, what is the differential diagnosis? A biopsy of the mass initially was performed 2 months after the onset of symptoms. The initial biopsy sections were interpreted as showing heterotopic ossification without evidence of malignant cells.

“…On MR images, the early changes are diffuse whereas later the lesion becomes well circumscribed. In these patients, the clinical history of recent trauma, maturation (zonation) pattern, absence of an expanding mass, and a self-limiting clinical course distinguish this lesion from calcific myonecrosis [4,25]. Dermatomyositis, polymyositis, and other connective tissue disorders frequently involve deposition of calcium in subcutaneous tissue, fascia, and muscle creating lesions that mimic calcific myonecrosis.…”

A 76-year-old man was referred for evaluation of a right lower leg mass. He reported an acute exacerbation of chronic pain in the affected limb. He had no recent injury or antecedent trauma but recalled a remote history of a right tibia fracture 60 years previously that was treated nonoperatively, with subsequent mild chronic leg pain attributable to the fracture. He stated that he had always perceived a 'knot' over the area since the injury, but that the knot had progressively enlarged during the last 3 months. His symptoms were activity-related but he also complained of weakness in the leg that had been present since the initial injury. He denied fevers, chills, night pain, or weight loss.
