The unusual radiographic pattern of bleblike mounds on the surface of the colon mucosa, previously described as colonic urticaria, was seen in 3 patients in whom no allergic state was present. This urticaria-like pattern was due to colonic distention in all 3, and represented only submucosal edema on the gross and microscopic specimens. We hypothesize that this pattern is due to early changes of ischemia caused by colon distention.
结肠黏膜表面出现的不寻常的放射学表现，即呈水疱样隆起，此前被描述为结肠性荨麻疹，在3例无过敏状态的患者中可见。这种荨麻疹样表现在所有3例患者中均由结肠扩张所致，在大体标本和显微镜标本上仅表现为黏膜下水肿。我们推测这种表现是由结肠扩张引起的早期缺血改变所致。
