“…In CC inverted diverticula have been described to cause inadvertent diverticulectomy because of their pseudopolypoid appearance (Fig. 5c, d) [15,20]; thus, it is important in case of an additional CC to inform the endoscopist of this finding.…”

The aim of this study was to evaluate findings on CT colonography (CTC) in patients with diverticular disease. In a retrospective analysis of 160 consecutive patients, who underwent CTC and conventional colonoscopy (CC), patients with diverticular disease were retrieved. The CTC images were compared with CC and, if possible, with pathology. Findings on both 2D and 3D images are illustrated with emphasis on diagnostic problems and the possible solutions to overcome these problems. Several aspects of diverticulosis were detected: prediverticulosis (3%); global (55.6%); and focal wall thickening (4%) caused by thickened haustral folds, fibrosis, inflammation and adenocarcinoma; diverticula (52%); pseudopolypoid lesions caused by diverticular fecaliths (39%); inverted diverticula (1.2%); and mucosal prolapse (0.6%). Solutions to overcome pitfalls are described as abdominal windowing, content of the pseudopolypoid lesion, comparison of 2D and 3D images, prone-supine imaging and the aspect of the pericolic fat. In this series there were equivocal findings in case of mucosal prolapse (0.6%) and focal wall thickening (4%). Diverticulosis is a challenge for CTC to avoid false-positive diagnosis of polypoid and tumoral disease. Knowledge of possible false causes of polypoid disease and comparison of 2D and 3D images are necessary to avoid false-positive diagnosis. In case of equivocal findings additional conventional colonoscopy should be advised whenever a clinically significant lesion (> or = 1 cm) is suspected.

“…The head of the diverticulum may prolapse into the lumen, causing a misleading macroscopic appearance, resembling a polypoid lesion, offering a true diagnostic challenge (10)(11)(12)(13)(14)(15). This phenomenon has been described with Meckel diverticula (16) and appendiceal intussusception (17).…”

“…There are a few reported cases, concerning inverted duodenal (5) and colonic diverticulum (10-15) diagnosed by UGIE. This "polypoid lesion" is described as being voluminous, soft, pliable, congestive, broad stalked, easily indented when probed with forceps biopsy, dimpling at the site of invagination, presenting the characteristic "pillow sign" with radiating folds and disappearing with application of gentle air insufflation (10)(11)(12)(13)(14)(15). The first recorded inadvertent endoscopic diverticulectomy of an inverted sigmoid diverticulum was made in 1982 (14).…”

“…It is of value to attempt to induce eversion of ICD using endoscopic air insufflation [5]; as we performed in our case or during radiological evaluation [6]. It is suggested to probe the lesion gently with biopsy forceps and attempt to push it outside the colon [7].…”

In spite of the rare incidence, inverted colon diverticulum can be misinterpreted and may result in perforation when biopsied or endoscopically removed. Such iatrogenic perforation can be avoided by simple maneuvers. Endoscopic air in insufflation can simply detect inverted colon diverticulum and save the risk of perforation. Our case study represents an old lady scheduled for colonoscopy for advanced evaluation of ambiguous abdominal pain and constipation. A polyp was discovered in the sigmoid colon. By air insufflation, the inverted colon diverticulum was detected and further procedures were ceased.
