36-year-old female with left ankle pain and swelling. TENDONS: The Achilles tendon is normal. The medial tendons appear normal. The peroneus longus tendon appears slightly enlarged as it courses behind and beneath the distal fibula, which may reflect mild tendinosis, but this is equivocal. The peroneus brevis tendon appears intact. Anterior tendons are normal. LIGAMENTS: The ligaments of the lateral collateral complex appear normal. The anterior tibiofibular ligament appears intact. The posterior tibiofibular ligament is less well-defined than usual on the axial sequences with a small adjacent collection of fluid signal intensity, suggestive of a ganglion. These findings may reflect degeneration or prior injury to the structure, but are not necessarily of any current clinical significance. The visualized components of the deltoid ligament complex appear intact.ARTICULAR SURFACES AND BONE: The bones appear normal. We see no osteochondral defect. There is a small amount of fluid within the tibiotalar, subtalar and talonavicular joints, not necessarily of any clinical significance. ADDITIONAL
1.Mild soft tissue edema as described above is nonspecific.2.Slight prominence of the peroneus longus tendon may reflect mild tendinosis, but this is equivocal.3.The posterior tibiofibular ligament is less distinct than usual, with an adjacent subcentimeter collection of fluid intensity, which may represent a small ganglion. This may represent degenerative change or prior injury, but is not necessarily of any current clinical significance.
