Presentation
Patient presented with rectal bleeding and lower abdominal pain.
Patient Data
There is asymmetric colonic wall thickening seen involving a short segment of sigmoid colon, suggestive of a neoplastic process. There is an associated bubbly appearance of multiple rounded air-containing diverticula (in keeping with colonic diverticulosis) as well as peri-colic fat stranding and poorly-defined area of hazy increase in attenuation value of mesenteric fat (in keeping with diverticulitis).
Case Discussion
Endoscopic biopsy revealed a colonic adenocarcinoma and diverticulosis. Colectomy was carried out. Histopathology revealed adenocarcinoma and diverticulitis.
While there is no association between colorectal cancer and colonic diverticulosis 1-3, there is evidence of possible increased risk of colorectal cancer in patients with diverticulitis 4,5.
