Purpose or Case Report: We present a rare Case Report Exhibit of a 4-year child with myositis ossificans secondary to non-accidental trauma. The child presented to the ER complaining of a headache. Head CT was unremarkable. However, initial physical examination revealed numerous bruises over the lower abdomen and thighs including belt marks. The patient also demonstrated restricted range of motion. A skeletal survey showed multiple remote fracture deformities and myositis ossificans extending the length of both femurs. Although myositis ossificans frequently occurs in athletes who sustain blunt injury, this unfortunate case occurred secondary to non-accidental trauma and specifically the caregiver intentionally standing on the patient’s legs. Pediatric radiologists should be mindful of non-accidental trauma as a potential cause of myositis ossificans, especially in very young children and when multifocal.
