Foot ulcer There is superficial ulceration along the lateral midfoot overlying the base of the fifth metatarsal which does not appear to extend to the level of the cortex. There is no abnormal T1 signal intensity of the fifth metatarsal base to suggest osteomyelitis and the overlying cortex appears intact however there is increased STIR signal suggesting some reactive osteitis. The marrow signal intensity of the remaining metatarsals is normal.Images of the forefoot demonstrate moderate osteoarthritis of the first MTP joint with a mild hallux valgus deformity. There is diffuse soft tissue edema, skin thickening, and inflammation, particularly along the dorsum of the foot. No discrete fluid collection is identified.
Superficial ulceration along the lateral midfoot overlying the base of the fifth metatarsal without definite evidence of osteomyelitis. Abnormal signal intensity within the fifth metatarsal is thought to represent reactive osteitis.
