Extreme abdominal distention episodes. no distention on ct (no air, fluid, or distended bowel...nothing). what could cause this confusing result?

Chameleons vs Static: Humans change status. 2 issues: (1) like most medical tests, only issues present at moment of the test show; not previous or future issues. (2) the range of "normal" (as defined by medical industry: the central 96% of usual) is huge. I have seen many examples of radiologists calling images normal when the issue is quite visible within the images. Get ; examine the images yourself with assistance.
