MRI of subcutaneous abscesses in the limbs pre and post treatment. MRI of the left femoral showed two different fluid collections extended along the path of subcutaneous connective tissue (upper panel, A and B). There was a spot with slightly high signal at the lower end of the left humerus (middle panel, D). After the comprehensive treatment, the left femur and the left humerus abscesses faded away obviously (C and E). Another mass was on the right femur above the right popliteal fossa, without fluid fluctuation (lower panel, F and G). After surgical removal of the abscesses, the abscess lesion on the right humerus was restored (H)
