A 40-year-old male weightlifter presented with a 6-month history of a painless mass in the right deltoid. He had no history of trauma to the shoulder other than an arthroscopic rotator cuff repair a few weeks earlier. Physical examination showed a firm, nontender mass located longitudinally and coinciding with the deltoid, measuring 12×14×4 cm. There was no limitation in range of motion or func...

Trigger point injection is a simple procedure that is widely performed for relieving pain. Even though there are several complications of trigger point injection, myositis ossificans has not been documented as one of its complications. We treated a patient who suffered from painful limitation of elbow motion and this was caused by myositis ossificans between the insertions of brachialis and sup...

Myositis ossificans is a benign ossifying process in the musculature presenting a typical zonal pattern of mineralization. It is difficult for diagnosis at early stage because of atypical imaging finding. CT scan examination is more sensitive than radiography for detection of ossification. However, MR imaging presentation of the early lesion is non-specific, which makes it difficult to distingu...

Neurogenic myositis ossificans is a disabling condition affecting the large joints of patients with severe post-traumatic impairment of the central nervous system. It can result in ankylosis of the joint and vascular or neural compression. Surgery may be hazardous with potential haemorrhage, neurovascular injury, iatrogenic fracture and osteochondral injury. We undertook pre-operative volumetri...

Illingworth, R. S. (1971). Archives of Disease in Childhood, 46, 264. Myositis ossificans progressiva (Miinchmeyer's disease): a brief review with report of two cases treated with corticosteroids and observed for 16 years. Two cases of myositis ossificans progressiva were treated by corticosteroids. In one case the course of the disease was not affected. In the other case, after 5 years' progre...

A 35-year-old man presented to the emergency department complaining of right hip pain after being struck by a car while crossing the road. His vital signs were stable, and he complained of right hip pain. He had no other comorbidity. On examination, tenderness and reduced abduction were noted in his right hip, but the gait was normal. The plain radiograph of his pelvis revealed a large, well-ci...

Myositis ossificans circumscripta (MOC) is an extra-osseous non- neoplastic growth of a new bone. It occurs most commonly in the second and the third decade of life, while it is rare in children. The etiology of MOC is unknown and the quadriceps and brachials are the most affected. The occurrence of traumatic MOC in tissues of the neck is uncommon. We are presenting below a rare case of traumat...
