Intussusception in adults is a rare pathology due to the telescoping of a bowel segment into a section adjacent to it. Almost all cases are linked to a pathological lead point, which is often a colorectal carcinoma where the intussusception involves the large intestine. Likely to occur in the same clinical setting, the differential diagnosis between intussusception and colon carcinoma by ultrasound in the emergency department can be quite challenging. We present a rare case of transient colonic intussusception with a well-differentiated colon adenocarcinoma as the lead point in a 43-year-old patient. The point of care ultrasound (POCUS) revealed the target sign characteristic of intussusception at the level of maximum pain, associated with a pseudokidney sign. However, the pseudokidney sign was indeed an adenocarcinoma of the ascending colon visualized by colonoscopy and per op.
成人肠套叠是一种罕见的病理状况，是由于一段肠管套入与其相邻的肠段所致。几乎所有病例都与病理性引导点有关，该引导点通常是结直肠癌，此时肠套叠累及大肠。肠套叠和结肠癌在急诊科通过超声进行鉴别诊断可能颇具挑战性，因为它们可能出现在相同的临床情况下。我们报告了一例罕见的短暂性结肠套叠病例，该病例以一名43岁患者的高分化结肠腺癌作为引导点。床旁超声（POCUS）在最大疼痛部位显示出肠套叠特有的靶征，并伴有假肾征。然而，该假肾征实际上是通过结肠镜检查和术中所见的升结肠腺癌。
