Case Report - Myositis Ossificans: Two Case Presentations


SG Lungu

Abstract

Myositis Ossificans [MO], a florid ossification, may occur in muscles and soft tissue. It is also called by many different names. The lesion contains actively proliferating fibroblasts and osteoblasts and early in its development may be confused with a malignant tumor. It commonly affects vigorous young men and more so among athletes. Most often involved are the flexor muscles of the arm and the quadriceps femoris. By time of presentation, ossification is extensive and the benign nature of the lesion is usually evident on radiological studies. This paper presents two cases. While literature shows that MO is common in the flexor muscles of the arm, the hamstrings and quadriceps femoris, it is noted that other muscles of the thigh and around the hip joint can also be affected as demonstrated in the two cases presented here.

Keywords: Myositis ossificans [MO], benign lesion, hip area and hip adductus muscles
