Sampathkumar K et al. - 50-year-old gentleman diagnosed as having diabetic nephropathy, with end-stage renal disease (ESRD) one year ago, was advised continuous ambulatory peritoneal dialysis (CAPD) in view of repeated access failure in hemodialysis.The X-ray showed diffuse punctate calcifications in the region of the colon along with the CAPD catheter in-situ .He was on lanthanum carbonate 500 mg thrice a day for his hyperphosphatemia.This phenomenon is important since misdiagnosis and endoscopic procedures can be avoided. This method can also be used to assess drug compliance.
