Right foot/ankle mass; chronic pain Ankle/hindfoot: There is slight prominence of the subcutaneous fatty tissue anterior to the lateral malleolus which could represent a lipoma but this is equivocal. There is otherwise no discrete mass identified. There is minimal edema of the subcutaneous fat about the ankle both medially and laterally. There is slight signal heterogeneity of the deep fibers of the deltoid ligament which may represent prior sprain. The remaining ligaments, tendons, and soft tissues are unremarkable.Midfoot/forefoot: Mild osteoarthritis affects the first MTP joint and there is a mild hallux valgus deformity. There is mild edema of the soft tissues at the bases of the first and second toes. A couple of small (less than 5 mm) foci of high signal intensity are seen lateral to the proximal phalanx of the second toe which are nonspecific in nature and may represent small ganglia or even nerve sheath tumors but are of questionable clinical significance. The location of these foci is slightly distal for the typical presentation of a Morton neuroma. The bone marrow signal intensity of the foot is normal.
1. Mild nonspecific soft tissue edema of the foot and ankle as described above.2. Prominence of the subcutaneous fat anterior to the lateral malleolus may represent a lipoma but this is equivocal. There is otherwise no discrete mass identified.3. Small foci of increased signal intensity lateral to the proximal phalanx of the second toe which are of uncertain clinical significance and etiology but may represent ganglia or perhaps nerve sheath tumors. Morton neuroma is considered less likely given the relatively distal location.
