Abstract

We present a case of an asymptomatic 70-year-old man with intussusception of the descending colon due to inflammatory myofibroblastic proliferation. Abdominal ultrasound examination showed a hypoechoic mass, 32 × 19 mm in size, accompanied by intussusception in the descending colon, and power Doppler sonography detected blood flow signals in the mass. Computed tomography revealed a hypervascular lesion, which was confirmed by barium enema and colonoscopy. The surgically excised mass was histologically diagnosed as inflammatory myofibroblastic proliferation. Although intussusception due to inflammatory myofibroblastic proliferation is rare, it should be considered in cases of adult colonic intussusception.

摘要

我们报告一例70岁无症状男性，因炎症性肌纤维母细胞增生导致降结肠套叠。腹部超声检查显示一个大小为32×19mm的低回声肿块，伴有降结肠套叠，能量多普勒超声在肿块中检测到血流信号。计算机断层扫描显示一个高血管病变，钡灌肠和结肠镜检查证实了这一点。手术切除的肿块经组织学诊断为炎症性肌纤维母细胞增生。虽然炎症性肌纤维母细胞增生引起的套叠很少见，但在成人结肠套叠病例中应予以考虑。
