45-year-old male with Achilles pain. Evaluate Achilles tendon. TENDONS: Best seen on the sagittal sequences is linear intrasubstance signal within the distal fibers of the Achilles tendon, suggesting mild tendinosis. There is also mild increased signal intensity along the posterior margin of the tendon, distally, suggesting a mild peritenonitis. There is flattening of the peroneus brevis tendon as it courses posterior and beneath the fibular tip, which may represent a partial-thickness longitudinal split tear. This is not necessarily of any current clinical significance as there is no suggestion of peroneal tenosynovitis. The flexor and extensor tendons appear intact. LIGAMENTS: The anterior talofibular ligament appears thinned, which may reflect an old injury. The calcaneofibular ligament appears intact. The posterior talofibular ligament appears intact. The distal tibiofibular syndesmotic complex appears intact. The visualized components of the deltoid ligament appear intact.ARTICULAR SURFACES AND BONE, AND OTHER
