retroperitoneal fibrosis usually gives uneven MRI signals, is bulky, extends above the origins of renal arteries, or displaces the aorta anteriorly. Additionally, malignant retroperitoneal fibrosis less frequently displaces the ureters medially when compared to other causes of retroperitoneal fibrosis.

The diagnosis of retroperitoneal fibrosis cannot be made on the basis of the results of laboratory studies. CT is the best diagnostic modality: a confluent mass surrounding the aorta and common iliac arteries can be seen. On MRI, it has low T1 signal intensity and variable T2 signal. Malignant

Although biopsy is not usually recommended, it is appropriate when malignancy or infection is suspected. Biopsy should also be done if the location of fibrosis is atypical or if there is an inadequate response to initial treatment.
