case_images: On follow-up computed tomography (CT) scan of the abdomen and pelvis a year later, he was found to have a bladder mass (Fig. 1). TCC. Three weeks later, a follow-up CT scan of the abdomen and pelvis was performed for routine follow-up of the rectal cancer; this scan incidentally detected calcification of the bladder wall at the surgical resection site (Fig. 1).
case_images: Cystoscopy revealed extensive whitish calcification of the bladder wall, especially at the previous surgical resection site.

case_images: Extensive stone-like, whitish calcification of the bladder wall at the surgical resection site was found (Fig. 2), not merely slough or soft tissue material.
case_images: Histopathology images of resected bladder calcification areas.
  A. Concretions forming large solid islands in a background of fibrosis and inflammation (HE stain, 20x). B. Large sheet-like area of foreign material/concretions (upper field), with a multinucleated giant cell (heavy arrow) and two small concentric concretions (thin arrows) in the foreground (HE stain, 40x).
