Two bladders, two colons and two uteruses.

Complete colonic duplication is rare and frequently asymptomatic. We present an interesting case of tubular colonic duplication with associated uterine didelphys and a longitudinal sagittal septum in the bladder, noted incidentally on cross-sectional imaging. The patient was later diagnosed with ulcerative colitis affecting the duplicated colon and is currently in remission following medical therapy.
