Radiologic Findings of Localized Amyloidosis of the Ureter: A Case Report
Abstract:
Amyloidosis is characterized by extracellular deposition of abnormal proteinaceous material. Localized amyloidosis in the urogenital system, particularly in the ureter, is rare. Localized amyloidosis of the ureter is often confused with other conditions such as urothelial carcinoma because of similar radiological findings. We report a case of an asymptomatic 74-year-old female who demonstrated multifocal wall thickening of the unilateral ureter and ureterovesical junction on CT and and was mistaken for urothelial carcinoma; however, her condition was diagnosed as localized amyloidosis of the ureter by surgical resection.
