title: Amyloidosis presenting as a perforated giant colonic diverticulum.
abstract: 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.
