CT and MR imaging in the evaluation of retroperitoneal fibrosis

J Comput Assist Tomogr. Mar-Apr 1989;13(2):277-81. doi: 10.1097/00004728-198903000-00018.


We have performed CT and MR on five patients with biopsy proven retroperitoneal fibrosis (RPF). Magnetic resonance (MR) accurately displayed a retroperitoneal mass of low signal intensity on T1-weighted scans and of heterogeneous medium signal intensity on T2-weighted scans. The coronal MR views demonstrated a retroperitoneal mass: the shape, signal intensity, and effects on the ureters and major vessels appear characteristic of RPF.
