Achilles tendinopathy and ankle pain TENDONS: There is increased intrasubstance signal and thickening of the Achilles tendon particularly its insertion upon the calcaneus. Small areas of near fluid signal intensity are seen as well suggesting some intrasubstance tearing superimposed upon diffuse tendinopathy. There is no evidence of full-thickness tear. Abnormal increased signal and thickening also affects the peroneus brevis tendon suggesting tendinopathy with probable split tearing. The remaining flexor and extensor tendons are intact.LIGAMENTS: The anterior tibiofibular ligament is poorly delineated which may be the result of chronic or remote tearing. The anterior and posterior talofibular ligaments are intact.ARTICULAR SURFACES AND BONE: Mild osteoarthritis affects the midfoot. The ankle mortise is intact.ADDITIONAL
1. Partial tearing and tendinopathy of the Achilles tendon upon its insertion on the calcaneus.2. Tendinopathy and split tearing of the peroneus brevis tendon.
