Myositis ossificans is characterised by a benign ossifying lesion in soft tissue mass, most commonly preceded by a muscle contusion in the thigh. Despite the fact that it is often a self-limiting disease, treatment modalities are anti-inflammatory drugs, physiotherapy, shockwave therapy, radiation therapy or surgical resection. We report a 22-year-old competitive football player with severe ongoing pain in the lower leg after a direct trauma. An X-ray showed calcification between the tibia and fibula. An additional ultrasound confirmed the diagnosis: myositis ossificans of the tibialis anterior muscle. After treating him with anti-inflammatory drugs and physiotherapy, he was able to return to sports. Myositis ossificans of the lower leg is an uncommon, though if present, troublesome condition, occurring after a contusion. ER -
