The bone marrow of the great toe proximal phalanx head and neck shows abnormal signal (low on T1 and high on T2/PDfs).
Skin ulcer with oedema and thickening of subcutaneous tissue is seen at the great toe plantar aspect at the interphalangeal joint level.
Subcutaneous oedema and thickening are also seen along the dorsal aspect of the foot.
Case Discussion
