An atypical presentation of myositis ossificans

Abstract

In the following case study an atypical presentation of myositis ossificans (MO) in the superior anterolateral thigh of a young soccer player is discussed. This case demonstrates that MO can present without obvious history of trauma, which makes the diagnosis of this condition more challenging. The most important differential diagnosis is malignant osteosarcoma or soft-tissue sarcoma, which usually presents without trauma. Additionally both pathologies typically occur in the same population.
