68-year-old female with pain on ambulation and right foot swelling. TENDONS: The flexor and extensor tendons appear intact. The peroneal tendons appear intact. The Achilles tendon is within normal limits.LIGAMENTS: The lateral collateral ligament complex appears intact. The distal tibiofibular syndesmotic complex appears intact. The imaged components of the deltoid ligament appear intact. ARTICULAR SURFACES AND BONE: There is subchondral cyst formation within the medial tibial plafond. Osteoarthritis affects the tibiotalar joint. Severe osteoarthritis affects the second tarsometatarsal joint with underlying bone marrow signal abnormality likely degenerative in etiology. There is soft tissue swelling in the surrounding area. Additionally, there is also increased bone marrow signal abnormality identified more distally within the proximal metadiaphysis of the second metatarsal which is suspicious for stress reaction. There is no definite cortical disruption to confirm a stress fracture.ADDITIONAL
1. Osteoarthritis of the second tarsometatarsal joint and dorsal soft tissue swelling in the surrounding area.2. Possible stress reaction within the proximal metadiaphysis of the second metatarsal.
