The article was informative and highlighted some important features that the radiologist should be aware of when evaluating cecal volvulus on CT images. A cecal volvulus is the rotation or torsion of a mobile cecum and ascending colon, which causes approximately 1 to 3 percent of all large bowel obstructions . If untreated, cecal volvulus can progress to bowel ischemia, necrosis, or perforation . The clinical manifestations, diagnosis, and management of cecal volvulus are discussed here. ciﬁ c for cecal volvulus.

Cecal volvulus radiology

Demonstrated in this case is marked proximal bowel dilatation up to 10 cm with increase risk of bowel perforation and fecal peritonitis. The whirlpool sign (also known as the whirl sign) is seen when a structure twist on itself. (Left) Graphic shows a twist (volvulus) of the ascending colon, obstructing the lumen and blood supply. The cecum on the mesentery is dilated and displaced toward the left upper quadrant (LUQ). (Right) Supine radiograph shows a gas-distended segment of bowel (cecum) within the mid abdomen. The large loop of dilated bowel in the central abdomen is the volved cecum, with a resultant small bowel obstruction. This film is made more challenging by the gas retained in the semi-dilated ascending colon.

On axial CT images, cecal volvulus is suggested by the extreme dilatation of the cecum. When seen on conventional radiographs or tomograms, the cecal volvulus is seen as a rounded focal collection of air-distended bowel with haustral creases in the left upper quadrant that resembles a coffee bean (Figs. 2A, 2B, 2C and 3A, 3B).

Cecal volvulus is common among young patients than in elder patients, whereas it is the vice versa in sigmoid volvulus. In cecal volvulus, the cecum twists and inverts. The twist occupies the left upper quadrant of the abdomen.

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.

Cecal volvulus is common among young patients than in elder patients, whereas it is the vice versa in sigmoid volvulus. In cecal volvulus, the cecum twists and inverts. The twist occupies the left upper quadrant of the abdomen. The terminal end of the ileum is also twisted along with the cecum in most occurrences. Cecal volvulus has another

The CT topogram (Figure 1) revealed a loop of dilated, stool-filled bowel in the mid abdomen, confirmed to represent dilated cecum on coronal CT imaging ( Figure 30 Mar 2012 Summary: Radiologists have established many classic imaging signs A cecal volvulus can appear very similar to a sigmoid volvulus; 2 Mar 2020 A cecal volvulus is the rotation or torsion of a mobile cecum and ascending colon, which causes approximately 1 to 3 percent of all large bowel 13 Jan 2020 Cecal volvulus is a very rare cause of large bowel obstruction (LBO) that By contrast, radiographic imaging, including abdominal radiography There is a variant of cecal volvulus termed a "cecal bascule" that occurs when the cecum folds anteriorly without any torsion. A cecal bascule is often seen as a In these patients without ongoing intestinal obstruction, radiological diagnosis relies on the The colonoscope in cecal volvulus: report of three cases. Large-Bowel Obstruction in the Adult: Classic Radiographic and CT Findings, Colonic volvulus refers to torsion of the bowel around its own mesentery [1,2]. 11 Apr 2014 Caecal volvulus is a rare cause of intestinal obstruction, with the bascule and had characteristic radiological findings of a caecal volvulus—bascule subtype. Cecal volvulus: analysis of 50 patients with long-term Learning objectives. Describe the various radiologic imaging appearances of volvulus throughout the GI tract – stomach, small bowel, cecal and sigmoid colon – in 10 Oct 2018 In abdominal imaging it is commonly used to describe transition points volvulus or internal hernias.1, 2 In a small or large bowel volvulus for Imaging may also show that the appendix, which is attached to the cecum, is filled with air.

The diagnosis of cecal volvulus is confirmed surgically (Figure 3) and right hemicolectomy is performed with uneventful post-operative recovery.
