Left ankle pain Note that the exam is limited by motion artifact. TENDONS: No significant abnormality noted.LIGAMENTS: No significant abnormality noted.ARTICULAR SURFACES AND BONE: There is serpentine signal abnormality within the distal tibia extending to the articular surface, indicating osteonecrosis. This appears to be chronic in nature as there is no associated marrow edema. Additional chronic-appearing osteonecrosis is seen affecting the body of the talus posteriorly. Small foci of signal abnormality within the navicular and cuboid likely represent degenerative cysts. There is a small tibiotalar joint effusion with a small amount of fluid within the subtalar and talonavicular joints, all of which is not necessarily of any current clinical significance. ADDITIONAL
1. Diffuse nonspecific subcutaneous edema of the ankle.2. Small tibiotalar and subtalar joint effusions which are of questionable clinical significance.3. Chronic osteonecrosis of the posterior talus and distal tibia.4. Mild osteoarthritis of the midfoot.5. Normal appearance of the ankle tendons.
