Myositis Ossificans in psoas muscle after lumbar spine fracture.
Spine, 2009Co-Authors: Sang Woo Kim, Joon Hyuk ChoiAbstract:Study Design. A case report. Objective. To report a case of Myositis Ossificans in the psoas muscle after lumbar spine fracture. Summary of Background Data. Myositis Ossificans is a benign condition of heterotopic bone formation in skeletal muscle. It predominantly occurs in large muscles of extremities following injury. Occurrence in the psoas muscle is rare with no previous reports of this condition associated with vertebral fracture in patients without hematologic abnormality. Methods. A 56-year-old man was referred to our hospital for a mass located in the left psoas muscle and an L3 compression fracture. He complained of low back and left leg pain after a fall 2 weeks previously. Magnetic resonance (MR) imaging obtained 12 days after trauma showed an L3 compression fracture with a left psoas mass with low T1 and high T2 signal intensity, associated edema, and enhancement. Computed tomography (CT) scans showed a suspicious slightly high-density mass in the left psoas area. The radiologic features of the mass were consistent with a hematoma. Results. After 1 week, CT scans showed calcification at the hematoma site. Histologic examination following CT-guided biopsy demonstrated new bone formation, atrophy of skeletal muscle fibers, and fibrosis. Lymphocytes were focally infiltrating. Irregularly anastomosing bony trabeculae and fibroblastic cell proliferation were noted. On follow-up MRI and CT scans 2 months later, the previous calcified mass was no longer evident. Conclusion. Myositis Ossificans usually occurs in extremities and is very uncommon in the psoas muscle. We report psoas Myositis Ossificans that developed from hemorrhage and edema associated with a lumbar fracture and required only 2 months to regress completely. When one finds a soft tissue mass with surrounding edema in the psoas muscle combined with a vertebral compression fracture, Myositis Ossificans should be included in the differential diagnosis.

Myositis Ossificans of the chest wall simulating malignant neoplasm
The Annals of Thoracic Surgery, 2000Co-Authors: Yong Han Yoon, Wan Ki BaekAbstract:Myositis Ossificans originating from the chest wall is extremely rare. We report a case of Myositis Ossificans occurring in a young woman with progressive painful swelling in the chest wall. Preoperative examination suggested a malignant neoplasm originating from soft tissue. Although rare, Myositis Ossificans is one of the potential causes of painful swelling in the chest wall, and can be mistaken for a malignant neoplasm.

Treatment of Traumatic Myositis Ossificans with Acetic Acid Iontophoresis
Physical therapy, 1992Co-Authors: Deborah L WiederAbstract:The purpose of this case report is to document the treatment of a patient who had traumatic Myositis Ossificans with acetic acid iontophoresis. A 16-year-old boy developed quadriceps femoris muscle Myositis Ossificans as a result of a springboard diving accident. A 2% acetic acid solution was administered via iontophoresis into the Myositis Ossificans, followed by 8 minutes of pulsed ultrasound at 1.5 W/cm2. The treatment was performed three times per week for 3 weeks. At the conclusion of the treatments, radiographic findings indicated a 98.9% decrease in the size of the ossified mass. The patient regained full range of motion and was able to return to pain-free activity. This case report demonstrates the potential for a therapeutic program of acetic acid iontophoresis and ultrasound in eliminating Myositis Ossificans.

Myositis Ossificans of InfraorbitalMusculature in Uncontrolled Diabetic
2014Co-Authors: Mohan Baliga, Joanna BaptistAbstract:Myositis Ossificans traumatica is a form of dystrophic calcification that leads to heterotopic ossification of intramuscular connective tissue. It is rare in the orofacial region. A history of trauma, conventional radiography and computed tomography, along with histopathological examination, can be used effectively to diagnose this condition. We present a unique case of infected Myositis Ossificans traumatica in the infraorbital region in an uncontrolled diabetic.
