Reason: R/O Rupture History: Posterior tibial tendonitis . Pain. Inability to bear weight on right foot x2 years. Right ankle/midfoot:The anterior tendons appear intact. The flexor tendons appear intact. Specifically, the posterior tibialis tendon appears intact. There is a longitudinal split tear of the peroneus brevis at the level of the distal fibular tip, however, the tendon can be traced to the level of its insertion on the tuberosity of the fifth metatarsal. There is, however, linear fluid signal intensity within the tendon just proximal to the level of its insertion, indicating an additional interstitial tear. There is mild subcutaneous edema in the surrounding area. The lateral collateral ligament complex appears intact. The distal tibiofibular syndesmotic complex appears intact. The imaged components of the deltoid ligament appear intact. There is a lobulated focus of fluid signal intensity along the dorsal aspect of the base of the fifth metatarsal which may represent ganglion formation. No osteochondral defect is identified. No bone marrow signal abnormality is seen.Right midfoot/forefoot:Mild osteoarthritis affects the first MTP joint including subchondral cyst formation within the first metatarsal head. There is heterogeneous signal abnormality along the dorsal aspect of the first metatarsal head which likely represents postsurgical change related to prior bunionectomy. There are skin markers in the adjacent area which presumably correspond to the patient's surgical scar, per the technologist note. No enhancing mass lesions are identified. No bone marrow signal abnormality is seen.
Longitudinal split tear and interstitial tearing of the peroneus brevis as described above. The posterior tibialis tendon appears intact. Osteoarthritis and postsurgical changes affect the foot.
