Calcified neonatal renal vein thrombosis demonstration by CT and US

摘要

Two cases of calcified renal vein thrombosis (RVT) were diagnosed, incidentally, within the first weeks of life. The CT images present the virtually diagnostic branching pattern of calcification that has been previously noted on pathology specimen radiographs. The CT and US images show peripheral renal vein, central renal vein and inferior vena cava calcification conforming to the two theoretical origins of intravascular calcification. The patients had normal laboratory results and no symptoms related to renal vein or inferior vena cava thrombi.
