On CT, a thickened intestinal wall configured with a middle layer of low attenuation surrounded on each side by layers of higher attenuation has been termed the target sign. The presence of fat within the submucosal layer of the small intestine is a well-known manifestation of Crohn's disease, but has not been reported in other chronic intestinal diseases. We describe CT findings of fat density target sign in a patient with prior radiation.
在CT上，肠壁增厚，中间层呈低密度，两侧被更高密度的层所包围，这种表现被称为靶征。小肠黏膜下层存在脂肪是克罗恩病的一种众所周知的表现，但在其他慢性肠道疾病中尚未见报道。我们描述了一名曾接受过放疗的患者出现脂肪密度靶征的CT表现。
