RADIOLOGY: VASCULAR: Case# 33987: ?PTLD. This patient had renal transplant in 1/96. He presents with elevation in creatinine level. 1. Mildly echogenic renal transplant. RIs range from 0.64 to 0.77.2. Small hypoechoic area at the region of the renal vein anastomosis. This most likely is extrinsic to the renal vein. The flow at this location is three times higher than the renal vein near the hilum, creating a 3:1 gradient representing at least a 50 to 75% stenosis. This may be a small mass versus post-surgical changes and can be followed by ultrasound as clinically indicated.
