Common iliac artery stenosis after renal transplantation is a rare complication; it can occur in the course of hypertension and renal dysfunction. We report a case of suspected renal allograft rejection with iliac artery stenosis proximal to a transplanted kidney. A 52-year-old man with a history of cadaveric kidney transplantation 26 years previously underwent a second cadaveric kidney transplantation in the left iliac fossa because of graft failure 3 years before. In June 2012, the patient had progressive renal dysfunction. In July, a percutaneous needle biopsy was taken, and it showed no rejection; however, his renal function continued to get worse through September. A percutaneous allograft renal biopsy was performed under ultrasound guidance and showed hyperplasia of the juxtaglomerular apparatus and renin granules. Magnetic resonance angiography was used to evaluate the arteries in the pelvis and showed left common iliac artery stenosis, and a stent was placed. After percutaneous intervention, the patient's ankle brachial pressure index was within the normal range and the allograft function had improved.
