Document Summary
The most common abdominal malignancy and the most common solid renal tumor in pediatric patients. Peak incidence is 2. 5 years to 3 years of age. 2 to 8 times more common in patients with horseshoe kidney. Up to 40% of patients with wilms" tumors have renal vein thrombosis and/or vena cava or atrial thrombus at the time of diagnosis. Venous obstruction may result with findings of leg edema, varicocele, or budd-chiari syndrome. The most common of all renal neoplasms. Twice as common in men; develops in the 6th or 7th decade of life. Solid or complex isoechoic or hyperechoic lesion. The larger the tumor, the more heterogeneous its echotexture, due to intratumoral hemorrhage and necrosis- appear as complex components. Tumors <3 are usually hyperechoic; distinguishing them from echogenic fat containing tumors are similar to angiomyolipomas is difficult. Hypoechoic rim= vascular pseudocapsule on color doppler. Presence of intratumoral calcifications are specific for rcc.
