Reason: left ankle injury 3 weeks ago persistent swelling and pain History: pain and edema TENDONS: There is a small amount of fluid within the peroneus longus tendon sheath. The peroneal tendons appear intact. The flexor and extensor tendons appear intact. The Achilles tendon is normal in appearance.LIGAMENTS: The proximal fibers of the ATFL are not well visualized and likely disrupted. The PTFL appears intact. The calcaneofibular ligament appears intact. There is loss of the normal fatty striation of the visualized components of the deep component of the deltoid ligament indicating prior injury or sprain. The distal tibiofibular syndesmotic complex appears intact.ARTICULAR SURFACES AND BONE: There is increased bone marrow signal abnormality within the medial aspect of the body of the talus. Additionally, there is apparent cortical disruption along the medial aspect of the posterior facet of the talus which may represent a small nondisplaced fracture (image 25 and 26; series 901).ADDITIONAL
1. Bone marrow edema within the body of the talus as well as cortical irregularity along the medial aspect of the posterior facet of the talus, which may represent a small nondisplaced fracture.2. Disruption of the ATFL.3. Loss of the normal fatty striation of the deep component of the deltoid ligament indicating a sprain or prior injury.
