title: [Inflammatory pseudotumor of the ureter: a case report].
abstract: A 57-year-old male was admitted because of the right flank pain. The image examinations, retrogradeurography, abdominal CT and MRI, showed a mass located at the upper right ureter. Although the tumor was not typical as ureteral cancer, we could not make a diagnosis of a benign tumor by image examinations. Therefore nephroureterectomy that was surgical method for ureteral cancer was performed. The tumor was diagnosed as inflammatory pseudotumor of the ureter by histological findings. Inflammatory pseudotumor is extremely rare for ulogeital organs. And this lesion is difficult to distinguish from malignancy only by image examinations. Therefore, the surgical resection and pathological studies are necessary.
