Intravenous lipoma of the inferior vena cava is an incidental finding on contrast-enhanced computed tomography in 0.5% of individuals. We report a case of multiple intravenous lipomas discovered during diagnosis of cholangitis in a 39-year-old woman. Imaging revealed three fatty masses that appeared connected by cordlike structures: one in the left renal vein with wide mural attachment and two in the inferior vena cava, the higher of which was mobile. We hypothesize that these originated as a single lipoma that subsequently divided into three distinct masses. Because mobile masses may cause pulmonary thromboembolism, surgery is recommended in these cases.
