60-year-old female with no history of trauma with redness and right ankle pain inferior to the medial malleolus for 3 to 4 days. There is mild soft tissue swelling along the medial aspect of the ankle, but we see no fracture. There is also opacification of the pre-Achilles fat and anterior margin of the Achilles tendon is indistinct. While this may reflect diffuse edema, we cannot exclude the possibility of Achilles tendon injury. If further imaging is clinically warranted, MRI could be considered.
