Abstract
In the following case study an atypical presentation of myositisossificans (MO) in the superior anterolateral thigh of a youngsoccer player is discussed. This case demonstrates that MO canpresent without obvious history of trauma, which makes thediagnosis of this condition more challenging. The most importantdifferential diagnosis is malignant osteosarcoma or soft-tissuesarcoma, which usually presents without trauma. Additionallyboth pathologies typically occur in the same population.Keywords: case report, ossification, osteosarcoma
Highlights
Myositis ossificans (MO) is defined as a localised formation of heterotopic non-neoplastic bone in muscle or soft tissue.[1]. It usually presents as a complication of traumatic muscle injury and is most likely to develop in high-risk sites of injury such as the quadriceps and biceps muscle
A 21-year-old male recreational soccer player presents with a three-week history of right hip pain during kicking, sprinting and climbing stairs, preceded by eight months of stiffness
Since the patient has recovered to his previous level of participation in myositis ossificans (MO) is a known complication of muscle injury where calcification proceeds to ossification in muscle or soft tissue.[2]
