Common pitfalls of WE-MDCT. a–c Localised poor distension of the proximal sigmoid colon (*) with apparent eccentric mural thickening (arrowheads) in a 61-year-old female with history of iatrogenic perforation during polypectomy treated with endoscopic clipping (arrow in a). Clinical and endoscopic follow-up was unremarkable. d–e Poor bowel cleansing with sparse intraluminal faecal residues from the rectum (in d) throughout the well-distended colon in a 68-year-old female with history of polypectomy. Subsequent endoscopic follow-up was also hampered by incomplete cleansing
