Reason: 40yo F w/ persistent foot discoloration, swelling, pain and concern for deep tissue infection History: as above The flexor and extensor tendons appear intact. The peroneal tendons appear intact. The Achilles tendon is normal in appearance. There is a small amount of fluid within the tendon sheaths as well as slight enhancement of the extensor digitorum longus, posterior tibialis, and flexor digitorum longus tendon sheaths indicating a mild tenosynovitis. There is a small amount of enhancing fluid within the tibiotalar and subtalar joints which may represent a mild synovitis. No bone marrow signal abnormalities are identified. The imaged musculature of the ankle and midfoot is unremarkable. There is nonspecific subcutaneous edema most pronounced along the dorsal aspect of the metatarsals. No focal fluid collection is identified to suggest abscess formation. There are no findings to suggest osteomyelitis. The distal tibiofibular syndesmotic complex appears intact. The ATFL is poorly visualized and likely disrupted. The PTFL appears intact. The calcaneofibular ligament appears intact. The imaged components of the deltoid ligament appear intact. There is a small amount of fluid within the retrocalcaneal bursa which may be of no clinical significance.
1. Nonspecific subcutaneous edema along the dorsal aspect of the foot may reflect a cellulitis in the correct clinical context.2. Findings indicating a mild tenosynovitis affecting the extensor digitorum longus, posterior tibialis, and flexor digitorum longus tendons. Other findings as described above.3. Probable disruption of the ATFL which may be chronic in etiology.
