Case of the Week: Retroperitoneal Fibrosis (Ultrasound & CT)

In this radiology lecture, we discuss the ultrasound and CT appearance of retroperitoneal fibrosis. Key points include: 1) Most cases (70%) are idiopathic = Ormond disease. 2) Nonspecific symptoms depending on involved structures: Malaise, weight loss, low-grade fever. 3) Ureteral entrapment: Obstructive uropathy or renal failure, may see medial deviation of middle third of ureters with hydronephrosis. 4) Venous entrapment: Lower extremity edema, deep venous thrombosis. 5) CT: Soft tissue mass anterolateral to aorta with posterior sparing. 6) DDx: Retroperitoneal Lymphoma will Lift the aorta. 7) MRI: Low T1/T2 signal when inactive, T2 bright with early enhancement when active inflammation. 8) PET/CT: Avid when metabolically active, may aid in identifying appropriate biopsy sites.
