Case report: calcified stones in right-sided colonic diverticula stimulating gallstones

Right-sided colonic diverticulosis, though unusual in the Western population, is common in the Orient. Calcified stones are rarely found within colonic diverticula. Standard textbooks of diagnostic radiology do not list calcified stones within caecal or ascending colonic diverticula as possible causes of calcification in the right hypochondrium or right iliac fossa. We present a patient with multiple laminated right-sided diverticular concretions mimicking gallstones. This possibility should be included in the differential diagnosis of gallstones or calcifications on the right side of the abdomen.
