Male, 74 years old. Pain, swelling TENDONS: The Achilles tendon is thickened with areas of internal abnormal signal, compatible with mild to moderate tendinopathy. A 6-7 mm cystic structure is noted within the tendon posteriorly approximately 2 cm from its insertion. A focus of fluid signal along the middle third of the Achilles tendon insertion on the calcaneus indicates a partial tear. There is moderate edema in the soft tissues surrounding the Achilles tendon. The other visualized tendons of the ankle had normal appearance.LIGAMENTS: The ligaments of the ankle are intact.ARTICULAR SURFACES AND BONE: There is marked bone marrow edema of the calcaneus centered on the Achilles tendon insertion, likely related to the tendon injury as described above. No discrete fracture line is identified. There is a small osteochondral defect at the medial talar dome. Additional degenerative changes are noted particularly involving the cuneiform-metatarsal articulations. There is a small tibiotalar joint effusion.ADDITIONAL
1.Partial tear of the Achilles tendon insertion is likely subacute in nature on a background of mild to moderate tendinopathy. Bone marrow edema in the calcaneus is likely secondary to the Achilles tendon insertion injury.2.Medial talar dome osteochondral defect and additional degenerative changes throughout the forefoot and midfoot.
