Axial and coronal reformatted CT images show a dilated cecum, with a visible air-fluid level, located in the left upper quadrant.
In the mid-abdomen, there is a mesentery twist ("whirl" sign) around the ileocolic artery.
There are no colonic loops on the right side of the abdomen, and there is decompressed descending colon in the left upper quadrant.
The small intestinal loops are located in the right hemiabdomen.
The afferent and efferent loops of the volvulus make up the X-marks-the-spot sign.
Post-surgical changes due to partial gastrectomy are identified.
Ascitic fluid is identified in the peri-splenic space and in the pelvic cavity, which has a density of 3 HU. Nodules are also identified in the mesentery of the right sub-diaphragmatic region that reaches up to 8 mm in diameter.
The uterus is absent.
