Introduction
In enhanced CT imaging of the small intestine in Crohn's disease, typical findings include thickening of the intestinal wall, mesenteric lymph node enlargement, and prominent vascularity within the bowel wall. Crohn's disease may be triggered by low immune function. After onset, inflammatory changes commonly occur in the adjacent mesentery. In addition, during treatment, patients should avoid consuming pickled and greasy foods.
Crohn's disease typically presents on contrast-enhanced CT of the small intestine as thickening of the intestinal wall, mesenteric lymph node enlargement, and visible blood vessels in the bowel wall.
1. Intestinal Wall Thickening
Crohn's disease may be triggered by low immune function. After onset, inflammatory changes often occur in the adjacent mesentery. This is particularly evident on abdominal CT scans, which show thickening of the small intestinal wall.
2. Mesenteric Lymph Node Enlargement
The pathogens associated with Crohn's disease are likely to invade the mesentery and local lymph node tissues. Therefore, CT imaging may reveal enlarged mesenteric lymph nodes.
3. Visible Vessels in the Bowel Wall
Crohn's disease may be closely related to bacterial infection or genetic factors. The disease can lead to pathological changes in mesenteric blood vessels, which appear clearly on CT scans as visible vessels within the bowel wall. As a relatively unique condition, Crohn’s disease can be treated with corticosteroids and immunosuppressive agents.
In addition, during treatment, patients should avoid pickled and greasy foods, and instead consume more foods rich in vitamins and high-quality proteins.
