Hemangioma in the Anterior Thigh With Corresponding Periosteal Bone Reaction

A 24-year-old female runner presented to physical therapy via direct access with an 8-month history of mid-thigh pain. At the onset of her symptoms, radiographs were negative; following physical therapy evaluation, additional imaging was requested. Lateral-view radiographs revealed cortical hypertrophy with no stress fracture. Magnetic resonance imaging revealed an enhancing mass adjacent to the anterolateral surface of the mid shaft of the femur, with associated cortical hypertrophy, consistent with a deep intramuscular hemangioma.
