Plain radiographs of the left lower leg and ankle. (A) Six weeks after the onset of skin lesions, substantial calcifications were visible in the posterior tibial artery and a network of small vessels in the retromalleolar region, near the skin lesions. (B) After 11 months, the vessel calcification in the retromalleolar region was almost completely resolved and calcification in the posterior tibial artery showed apparent regression. (C) After a subsequent 11 months of cinacalcet treatment, the posterior tibial artery demonstrated further calcification regression.
