A 56-year-old man presented with a painless scrotal lump, enlarging over the preceding 1 month. The lump was roughly 1 cm in size, and located in his left hemiscrotum and separate from the testis. An ultrasound revealed an echogenic focus with dystrophic tissue calcification. Subsequent surgical excision and histopathological analysis revealed it to be late-stage myositis ossificans, a benign, extraosseous formation of the bone or cartilage. We report of only the second described case of myositis ossificans of the spermatic cord in the literature to date...

Melorheostosis is a rare, nonhereditary, benign, mesenchymal condition of unknown aetiology affecting the bones and surrounding tissues. A male patient complaining of left shoulder pain, swelling, and mildly limited range of motion has an exclusive combination of the classic dripping wax lesion in the scapula and the myositis ossificans-like lesion in the deltoid muscle; this combination is the first to be reported in the shoulder. Both lesions showed typical findings of melorheostosis in radiographs, CT, MRI, and bone scan...

Muscle is an important component of the muscle-tendon-bone unit, driving skeletal motion through contractions that alter the length of the muscle. The muscle and myotendinous junction (MTJ) are most commonly injured in the young adult, as a result of indirect mechanisms such as overuse or stretching, direct impact (penetrating or nonpenetrating), or dysfunction of the supporting connective tissues. Magnetic resonance (MR) imaging is widely used for assessment of muscle injuries. This review illustrates the MR imaging appearance of a broad spectrum of acute, subacute, and chronic traumatic lesions of muscle, highlighting the pathophysiology, biomechanics, and anatomic considerations underlying these lesions...

This case report describes the diagnosis, surgical treatment, and management of a patient with low-grade chondrosarcoma of the cervical spine that initially presented as myositis ossificans. Chondrosarcoma is rare in the cervical spine and in this patient, may have been the result of an injury from a motor vehicle crash. The management of this patient has been unusual in that a complete excision was not performed because the patient refused standard treatment.

Objective: To assess the outcome of long standing ulno-humeral dislocation managed by open reduction and stabilization with V-Y plasty. Methods: This cross sectional study included 14 patients with elbow dislocation that was more than 3 months without joint ankylosis, myositis ossificans or nerve injury. The surgical management not only included open reduction of the elbow joint, but also elongation of the triceps aponeurosis, collateral ligament repair along with the stabilization of the elbow joint...

Prognostication of quadriceps contusion is based on the patient's active knee flexion after the injury. Unlike ultrasonography, clinical grading does not define the extent of soft tissue injury and may provide inaccurate time for return to play. The purposes of this report are to describe the ultrasound findings of the different clinical grading of quadriceps contusion and document the return to play of each case. Seven patients were evaluated in this series. Results showed discrepancies in the disability time between clinical grading and ultrasound findings...

PURPOSE: The purpose of this study was to report characteristics and outcomes of surgical excision of symptomatic mature posttraumatic myositis ossificans in adult athletes. The hypothesis was that surgical excision of the ossified mass in these circumstances can effectively relief symptoms and result in return to high-level sports with minimal postoperative complications. METHODS: All operations involving excision of posttraumatic heterotopic ossifications performed between 1987 and 2015 were reviewed...

Aneurysmal bone cyst (ABC) is an expansile cystic lesion that may affect any bone of the skeleton. Although exceedingly rare, lesions with histomorphologic characteristics of an ABC have reportedly originated within soft tissue. Extraskeletal ABC may mimic a variety of benign and malignant lesions and can be confused with other more common or rare giant cell-rich tumors of soft tissue, especially myositis ossificans. Clinical, radiological and histologic correlation is crucial in reaching the correct diagnosis...

A 77-year-old male who had had an olecranon fracture 15 years ago presented himself with mild pain of the right elbow. Physical examination revealed painless hardening of the finger and wrist flexors in an area of 10 cm from the origin. Conventional radiographs showed a mature myositis ossificans.

Myositis ossificans traumatica is a rare disease associated with chronic wounds and fistulae. Chronic ulcers, fistulae and wounds can transform into squamous cell carcinoma, the so-called Marjolin's ulcer. We describe a rapid, progressive and fulminant course of a metastatic squamous cell carcinoma arising from a chronic wound in a patient with myositis ossificans traumatica.

We report a case of a 29-year-old man who had been a victim of a public road accident. Four weeks later, the patient developed an isolated right thigh mass located ventrally in the distal one-third of the thigh. The mass was painful and associated with fever and inflammatory syndrome. Plain radiographs showed a bilateral calcified thickening of soft tissues with well-defined bony margins. Ultrasound objectified diffuse calcifications of soft tissues.CT scan-confirmed the diagnosis of myositis ossificans circumscripta, showing a bilateral thickening of the vastus intermedius chief of the quadriceps dotted with calcifications, extending along the femur axis...

INTRODUCTION: Heterotopic ossification occurs when bone develops in tissues which usually don't undergo ossification. Heterotopic mesenteric ossification, also known as intra-abdominal myositis ossificans, is a rare and benign form of ossification, usually related with previous abdominal surgery or trauma. PRESENTATION OF CASES: We report two cases of heterotopic ossification both after multiple abdominal surgeries, with intraoperative findings of mesenteric and abdominal wall ossification...

We report a case of a 23-year-old female with pain and fullness in the right popliteal fossa. An MRI scan demonstrated an ossified enhancing soft tissue mass. Evaluation of the resected specimen showed a high-grade extraskeletal osteosarcoma juxtaposed to the three zones of myositis ossificans. At 1-year follow-up the patient is alive and disease free. A review of the literature purporting to document such an association failed to demonstrate a single case in which an osteosarcoma and MO with its zonal architecture co-existed...

Background Myosits ossificans (MO) is a rare but important differential diagnosis for a heterotrophic bony tumor in the muscles. It is often misdiagnosed as a malignant tumor. With a previous trauma the diagnosis is myositis ossificans traumatic (MOT). In most cases, it is benign and predominantly seen in the big muscles. But there can be malignant etiologies too. Case Description We report a rare case of MO in the muscle of the craniocervical junction. This 37-year-old woman had a riding accident years ago...

A 61-year-old woman was admitted with severe hip pain causing immobility and high serum levels of inflammatory markers. The patient had a medical history of diabetes. She had been scheduled to undergo right hip replacement surgery for the treatment of osteoarthritis associated with gradually progressive pain. On admission, an enhanced abdominal computed tomography scan showed an abnormal increase in synovial fluid surrounding the right ilium, with piriformis muscle calcification. Subsequent blood and specimen cultures identified Campylobacter fetus subspecies fetus...

Myositis ossificans is a rare form of self-limiting heterotopic ossification of muscles. Most cases are seen in the thigh; the standard approach to these cases has been nonsurgical management awaiting spontaneous resolution. We report on a rare case of myositis ossificans of the hand with severe symptoms treated with early marginal excision without a trial of nonsurgical management.

Heterotopic ossification (HO, also termed myositis ossificans) is the formation of extra-skeletal bone in muscle and soft tissues. HO is a tissue repair process gone awry, and is a common complication of surgery and traumatic injury. Medical strategies to prevent and treat HO fall well short of addressing the clinical need. Better characterization of the tissues supporting HO is critical to identifying therapies directed against this common and sometimes devastating condition. The physiologic processes of osteogenesis and angiogenesis are highly coupled and interdependent...
