19 year-old female, with pain along third, fourth, and fifth metatarsals, evaluate for fracture Foot: There is mild soft tissue swelling and edema along the dorsum of the foot underlying the skin marker at the patient's site of symptoms. There is no significant bone marrow edema within the metatarsals to indicate a stress fracture. The bone marrow signal is normal throughout the foot.Ankle: Moderate tibiotalar joint effusion. The ATFL is not visualized and likely torn. The PTFL and calcaneofibular ligaments are intact. The inferior tibiofibular ligaments appear intact. There is edema within the medial talus and medial malleolus without discrete fracture line. There is also edema within the soft tissues along the medial and lateral aspect of the ankle beneath skin markers presumably placed at the site of patient's symptoms without underlying osseous abnormality. The extensor and flexor tendons including the Achilles tendon appear normal.
1. ATFL tear with marrow edema in the medial talus and medial malleolus, which may represent contusions as well as soft tissue swelling about the ankle.2. Soft tissue edema along the dorsum of the foot without evidence of fracture/bone marrow edema.
