This male football (soccer) player. Suffered a muscle contusion during a match in the lateral side of the thigh. The initial diagnosis was a vastus medialis muscle rupture with a hematoma. After 3 weeks he came to our medical services with a painful, tender, enlarging mass, located in the lateral side of the thigh (where the first injury was).
In the ultrasound examination we found a heterotopic calcification inside the vastus medialis muscle which was a myositis ossificans. We also made a CT scan to complete the diagnosis. CT images are similar to those of plain radiography, demonstrating mineralisation proceeding from the outer margins towards the center.
After a month, the evolution was correct and the patient was completely asymptomatic.
