Reason: left ankle cyst History: left ankle cyst TENDONS: A marker was placed along the medial ankle. The tibialis posterior tendon is enlarged indicating tendinosis. Additionally, there is a complete longitudinal split tear of the tendon as it courses posteriorly and deep to the distal fibula. Near-fluid signal intensity surrounding the tendon indicates tenosynovitis. The flexor digitorum longus tendon appears normal. Mild increased signal intensity within the flexor hallux longus tendon just distal to the talar tubercle likely represents focal tendinosis. The peroneal tendons are intact.LIGAMENTS: We see no acute ligament abnormality.ARTICULAR SURFACES AND BONE: Mild osteoarthritis affects the ankle and midfoot.
1. Tendinosis, longitudinal tearing, and tenosynovitis of the posterior tibial tendon.2. Mild osteoarthritis.
