Abstract

Primary localized amyloidosis of the ureter and bladder is a very rare condition. CT and cystoscopic findings are indistinguishable from malignant neoplasm or inflammatory lesions. We report a case of unilateral distal ureteral thickening caused by primary localized amyloidosis. MR image features of hypointensity on T2-weighted images and mural enhancing pattern on contrast enhanced T1-weighted images can be helpful for diagnosis of ureteral amyloidosis.

요관과 방광에 발생한 일차성 국소 유전분증은 매우 드문 질환이며, 전산화단층촬영과 요도방광경 소견상 악성 종양이나 염증성 병변들과 구분하기 어렵다. 저자들은 일차성 국소 유전분증으로 편측 원위부 요관이 비후된 증례를 보고하고자 하며, T2강조영상에서 저신호강도와 조영증강 T1강조 영상에서 벽의 조영증강형태가 요관 유전분증의 진단에 도움을 줄 수 있는 소견으로 생각된다.
