Often on CT scan
of abdomen, the stomach and colon may not be well distended. This may sometimes give the impression of wall thickening. Such wall thickening could represent anything from simple inflammation to tumor
. However, since a definite diagnosis of wall thickening can be made only in a reasonably well distended stomach/colon, the radiologist
has given both possibilities.
But, since there is no adjacent fat stranding (which usually occurs in association with wall thickening) and in view of you having had a normal colonoscopy
and EGD recently, there may not be much need to worry.
Overall, there may not be a cause of worry unless your symptoms don't improve in which case it maybe advisable to repeat a CT scan with proper distension of the stomach and colon.
