Abstract:
Objective To analyze the ultrasonographic features of retroperitoneal ifbrosis (RPF). Methods Totally 13 patients with retroperitoneal ifbrosis from February 2000 to October 2012 in the Long Gang central Hospital of Shenzhen were retrospectively analyzed. Results In all patients who underwent ultrasound examination, there were ten cases of idiopathic RPF and three cases of secondary RPF with abdominal tumors. In 11 cases, the masses were hypoechoic locating at retroperitoneum and surrounding the abdominal aorta without deifnitive margin. One case showed hypoechoic mass with clear boundary. In ten cases, the internal echogenicity of masses were uniform. In two cases, the internal echogenicity of masses were uneven with a small amount of ifbrous separator with slightly higher echogenicity. No blood was found in all masses. The encasement of inferior vena cava was found in three casesand the masses extended to iliac arteries in three cases. Hydronephrosis could be found in 11 patients (84.6%) and ureter dilatation was found in ten cases. Ureteral localized stenosis were found in two cases. Conclusion Ultrasonography is a preferred imaging method in diagnosing RPF.
