53-year-old female with left foot injury and pain for many years. Metallic susceptibility artifact related to the patient's orthopedic fixation of the first metatarsal limits evaluation. There are foci of signal void within the dorsal soft tissues about the first MTP joint likely postsurgical in etiology.TENDONS: The peroneal tendons appear intact. The flexor and extensor tendons appear intact. The Achilles tendon is normal in appearance.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 first metatarsal head and increased bone marrow signal abnormality about the first MTP joint, likely degenerative in etiology. Otherwise, no bone marrow signal abnormalities are identified. ADDITIONAL
1. Osteoarthritis of the foot as described above. 2. Subcentimeter focus of fluid signal intensity along the dorsal aspect of the base of the fifth metatarsal likely represents ganglion formation. 3. Postsurgical changes affecting the first metatarsal.
