Abstract
We report a case of idiopathic retroperitoneal fibrosis forming a localized tumor, which is relatively rare. A 55-year-old man was found to have a retroperitoneal tumor by abdominal ultrasonogram at a medical check up and was admitted to our hospital. On admission, he was asymptomatic and no physical abnormalities were seen. Abdominal CT scans revealed a mass in the left retroperitoneal space. The mass was confirmed to show low intensity on both Tl and T2 weighted images in MRI, which suggested fibrous component. Since a possibility of malignant tumor could not be still ruled out, the tumor was removed for the purpose of examination and treatment. The pathological diagnosis was idiopathic retroperitoneal fibrosis. The patient is strictly followed in the out patient clinic and no signs of recurrence have been observed. It is necessary to consider idiopathic retroperitoneal fibrosis in case of retroperitoneal localized mass.
