Cecal volvulus accounts for approximately 1 % of the intestinal obstruction. Etiology includes congenital development of fixation, secondary to adhesion, scarring or mass lesions. Two types of torsion are described: axial torsion and cecal bascule.

Demonstrated in this case is marked proximal bowel dilatation up to 10 cm with increase risk of bowel perforation and fecal peritonitis.

Courty (11) cites an additional 75 examples from France since 1940, and a review of the readily available sources in the American and British literature since 1942 has yielded 68 cases. 2020-03-27 · Two independent blinded readers retrospectively evaluated scans for cecal dilatation, ileocolic vascular curvature and seven previously reported CT features of cecal volvulus. Statistical methods included the exact binomial distribution to define 95% confidence intervals (95% CIs), logistic regression, receiver operating characteristic analysis, and the exact McNemar test. We read with interest the excellent article by Dr Rosenblat and colleagues on the findings of cecal volvulus at computed tomographic (CT) imaging in the July 2010 issue of Radiology. The article was informative and highlighted some important features that the radiologist should be aware of when evaluating cecal volvulus on CT images.

Operative note describes redundant cecum which had volvulized 3 turns. This likely occurred due to congenital lack of peritoneal fixation of the cecum, resulting in increased mobility. A few "flimsy adhesions" were noted in the operative note which may have served as a fulcrum for rotation. Cecal volvulus accounts for approximately 1 % of the intestinal obstruction.

Ileocolic vascular curvature and ectopic cecal location were the only features independently and significantly associated with cecal volvulus in multivariable regression (odds ratio 178, p = 0.014, and 63, p = 0.013, respectively) and also the only features with both sensitivity (12/14 [85.7%, 95% CI 57.2-98.2%] and 13/14 [92.9%, 95% CI 66.1-99 Radiology Masterclass 'Caecal Embryo Sign' In caecal volvulus, the dilated caecum takes on a shape similar to a mammalian embryo. That is, the formation of a large dilated caecal pole (head), with one or two further 'segments' (body and tail).

Volvulus of thececum and ascending colon is not as rare as is generally assumed. The early recognition of this type of colonic obstruction is of great importance for radiologist and surgeon alike. On axial CT images, cecal volvulus is suggested by the extreme dilatation of the cecum.
