	Description:		In this radiology lecture, we discuss the ultrasound and CT appearance of retroperitoneal fibrosis. Key points include: Most cases (70%) are idiopathic = Ormond disease. Nonspecific symptoms depending on involved structures: Malaise, weight loss, low-grade fever. Ureteral entrapment: Obstructive uropathy or renal failure, may see medial deviation of middle third of ureters with hydronephrosis. Venous entrapment: Lower extremity edema, deep venous thrombosis. CT: Soft tissue mass anterolateral to aorta with posterior sparing. DDx: Retroperitoneal Lymphoma will Lift the aorta. MRI: Low T1/T2 signal when inactive, T2 bright with early enhancement when active inflammation. PET/CT: Avid when metabolically active, may aid in identifying appropriate biopsy sites.
