Abnormal segment of dilated, fluid-filled small bowel in the right abdomen with associated mesenteric edema/interloop fluid. Two adjacent transition points entering and exiting this segment can be seen on the same axial image, consistent with closed loop configuration. Proximal to the narrowing entering the obstruction, there is a segment of mildly dilated small bowel mid abdomen. The proximal small bowel is relatively decompressed. Abdominal aortic aneurysm. Small amount of free pelvic fluid.
