Abstract:
A 58-year-old woman with poorly controlled diabetes, peripheral vascular disease, and end-stage renal disease requiring hemodialysis was referred for 18 F-FDG PET/CT to evaluate for source of sepsis. She had history of prior left forefoot and right second toe amputation, as well as left lower-limb dry gangrene for which she declined surgical management. We present a case of a nonamputated lower limb demonstrating regions of absolute photopenia, consistent with dry gangrene.
