Nonhealing ulcer There is mild diffuse edema of the subcutaneous tissues surrounding the ankle particularly overlying the anteromedial aspect of the distal tibia. Within this area is an irregular, rim-enhancing fluid collection which measures approximately 4 cm in total transverse dimension beginning just anterior to the flexor digitorum tendon and extending posteromedially. There is ulceration of the overlying skin in this area however there is no abnormal marrow signal intensity to suggest osteomyelitis. There is perhaps a trace amount of fluid surrounding the flexor digitorum tendon which is otherwise normal.Although not tailored for the examination of the ligamentous and tendinous structures of the ankle, these appear grossly intact.
Ill-defined rim-enhancing fluid collection within the anteromedial soft tissues overlying the distal tibia concerning for small subcutaneous abscess. There is no evidence of osteomyelitis.
