32-year-old female with pain following a fall, area in the right calcaneus concerning for lipoma on x-ray. TENDONS: The Achilles' tendon is intact. The anterior, peroneal, and medial tendons are intact. There is a small amount of fluid along the distal tibialis posterior tendon which may not be of any clinical significance.LIGAMENTS: The anterior and posterior talofibular ligaments appear intact. The calcaneofibular ligament appears slightly thickened which could conceivably represent a mild sprain but we suspect this is not of current clinical significance as there is no adjacent edema. The distal tibiofibular syndesmotic ligaments and the deltoid ligament complex appear intact.ARTICULAR SURFACES AND BONE: A heterogeneous lesion in the anterior aspect of the body of the calcaneus containing fat is consistent with an intraosseous lipoma. Additional nonadipose contents are seen within lipoma but overall this has the appearance of a benign lesion of no significance.Edema within the head, neck, and body of the talus most conspicuous in the lateral aspect of the head of the talus with there is suggestion of a linear component may represent a nondisplaced fracture, but this is equivocal. Edema is also concentrated along the medial aspect of the posterior process of the talus but we see no discrete fracture. Mild edema is also noted in the medial aspect of the tibial plafond, navicular tuberosity, medial calcaneus, cuboid, and medial aspect of the fifth metatarsal base without fracture evident.ADDITIONAL
1.Intraosseous lipoma of the calcaneus as described above.2.Multiple foci of marrow edema may reflect bone contusions with a possible nondisplaced fracture of the inferolateral head of the talus.
