Objective: Evaluate radiological findings on retroperitoneal fibrosis.
Patients and methods :A retrospective analysis conducted in the internal Medicine Department in Sahloul teaching Hospital between 1999 and 2016.Results: Thirty-two patients were included. There were 24 men and 8 women with a mean age of 58 years. Lower back pain is the most common symptom. Ultrasound showed a dilatation of the urinary cavities (n=16, 50%) and the CT scan confirmed the bilateral ureteral catheterization (n=11). A fibrous mass that surrounds abdominal aorta, the inferior vena cava and the iliac vessels was noted in CT scan (23 cases), in MRI (9 cases). Intravenous urography (IVU) noted ureteropelicillal dilation in 4 cases. Five patients suffered from RFP associated to pulmonary fibrosis (n=2), sarcoidosis (n=1), immunoglobulin G4-related disease (n=1), Riedel thyroiditis and orbital pseudo tumor (n=1).
Conclusion:The diagnosis of RPF is based on imaging, which seeks an etiology, an associated disease or a complication. CT-scan is the preferred imaging method. MRI may facilitate assessment of disease extent.
