Reason: foot ankle erythema, edema Ankle:Subcutaneous edema along the medial and lateral aspects of the ankle and enhancing reticulation of the subcutaneous fat along the heel may reflect cellulitis. Although the ankle edema becomes confluent we see no discrete rim-enhancing fluid collections to suggest a drainable abscess. We see no intra/inter-muscular fluid collections. The ankle tendons are intact. The study was not protocoled for ligamentous evaluation, however we see no discrete ligamentous injury. Loss of striation of the fibers of the deltoid ligament may represent a prior strain. Mild osteoarthritis affects the ankle and midfoot. The bone marrow signal is unremarkable.Foot:A focus of abnormal signal in the medial aspect of the first metatarsal head demonstrates enhancement following gadolinium administration and likely represents a degenerative cyst or perhaps chronic erosion. Mild thickening/enhancement of the medial capsular structures are seen, however we see no underlying soft tissue defect to suggest infection. The signal intensity of the remaining bones of the forefoot appears normal. There is mild edema of the dorsal subcutaneous fat of the foot but otherwise the soft tissue is unremarkable. Mild osteoarthritis affects the first MTP joint.
1. Cellulitis of the heel and ankle.2. Osteoarthritis and possible chronic erosion of the first metatarsal head but no specific radiographic findings of osteomyelitis.
