Myositis Ossificans of the Adductor Longus in a Soccer Player.

A 20-year-old male collegiate soccer goalkeeper presented to an athletic trainer during the season complaining of right (dominant kicking leg) groin pain. The athletic trainer identified a mass and hematoma and suspected myositis ossificans. The patient was referred to the team physician, who ordered radiographs and magnetic resonance imaging to confirm the diagnosis and rule out other injuries. Imaging demonstrated an adductor longus muscle strain with myositis ossificans. .
