Non-Traumatic Myositis Ossificans in the Lumbar Spine

Non-Traumatic Myositis Ossificans in the Lumbar Spine

BACKGROUND Myositis ossificans is a non-neoplastic benign reactive bone and cartilage matrix-producing pseudotumor that develops in skeletal muscles adjacent to the joint. The clinical and pathologic appearance of myositis ossificans varies depending on the time elapsed after heterotopic bone formation. Although its etiology is unclear, it usually occurs at the site of the injured muscle, most ...

Non-Traumatic Myositis Ossificans in the Lumbosacral Paravertebral Muscle

Myositis ossificans (MO) is a benign condition of non-neoplastic heterotopic bone formation in the muscle or soft tissue. Trauma plays a role in the development of MO, thus, non-traumatic MO is very rare. Although MO may occur anywhere in the body, it is rarely seen in the lumbosacral paravertebral muscle (PVM). Herein, we report a case of non-traumatic MO in the lumbosacral PVM. A 42-year-old ...

A Rare Case Of Non Traumatic Myositis Ossificans Circumscripta

INTRODUCTION Myositis ossificans circumscripta is a benign non neoplastic ossifying tumor presenting with bone like osteoid tissue extraskelletaly amidst the muscle planes. This condition when not associated with trauma is very trivial and considering the way it mimics certain characteristics, it may be misunderstood as a malignant neoplasm, abscess or antibioma. The aetiology of this atraumati...

Post traumatic myositis ossificans: Sonographic findings.

PURPOSE The aim of this paper is to describe the sonographic (US) features of post traumatic myositis ossificans (PTMO). METHODS Fifteen patients with histopathological diagnosis of PTMO were included. The following US parameters were evaluated: presence of a mass, calcifications, power Doppler signals, and relationship with adjacent structures. RESULTS Five patients (33.3%) were diagnosed ...
