Colonic amyloidosis is frequent, although rarely radiographically evident. The radiological findings are varied and unspecific. We report a case of perforated giant colonic diverticulum (GCD) diagnosed by helical CT in which amyloid deposition was pathologically demonstrated. The patient was a renal transplant recipient who previously had undergone hemodialysis for 10 years. A possible role of amyloidosis in the pathogenesis of this case is discussed. Giant colonic diverticulum must be included in the spectrum of gastrointestinal manifestations of amyloidosis.
结肠淀粉样变性很常见，尽管在影像学上很少有明显表现。其放射学表现多样且不具特异性。我们报告一例通过螺旋CT诊断为穿孔性巨大结肠憩室（GCD）的病例，病理证实有淀粉样蛋白沉积。患者是一名肾移植受者，此前已接受10年血液透析。本文讨论了淀粉样变性在该病例发病机制中的可能作用。巨大结肠憩室必须纳入淀粉样变性的胃肠道表现范围。
