Crohn's Ileitis

So here's some nice images from MR enterography in a patient who with a known history of Crohn's disease. Now notice that there is clearly thickening and edema of the terminal ileum, extending into the ileocecal valve, probably involving a roughly five or six -centimeter segments. Notice also that on the postcontrast images, this segment of bowel demonstrates avid hyperenhancement.

Now clearly there's Crohn's involvement of the terminal ileum. But I think it's more important to note that on MR, you can nicely delineate active inflammation related to Crohn's disease from chronic stricturing or narrowing of the terminal ileum. Now in this case, even though there is thickening and hyperenhancement, notice it on the T2-weighted images there is very little wall edema. So there's not much T2 hyperintensity, although there might be a little bit. And there's very little engorgement of the vasa recta or surrounding fat stranding in the right lower quadrant mesentery. So this is a case where there is clearly some degree of a chronic component, with perhaps only a mild degree of active acute inflammation.

这是克罗恩肠炎患者的磁共振小肠造影。可见回肠末端明显增厚和水肿，病变延伸至回盲瓣，累及范围大约五至六厘米。增强后可见病变部分明显强化。由此可知克罗恩病累及回肠末端。然而更为重要的是，磁共振清晰地勾勒了紧缩或狭窄的回肠末端中由克罗恩病引起的活动期炎症。虽然该病例可见增厚和强化，但T2加权像并未见明显肠壁水肿，信号轻微升高，且无明显直肠血管充血，右下腹肠系膜未见明显脂肪层渗液。因此该病例为慢性克罗恩病或伴轻度活动期急性炎症。
