CT OF ABDOMINAL BARIUM INTRAVASATION

We report a case of barium intravasation due to misplacement of the ca theter tip during a barium enema examination, leading to vaginal lacer ation and barium sequestration within the reticuloendothelial system o f a 57-year-old woman who survived this potentially fatal event. The r adiologic appearance on CT, sonography, MR, and plain radiography is p resented. Computed tomography demonstrated barium sequestered by the l iver, spleen, and renal cortex. The portal veins were seen as branchin g radiolucent densities superimposed on a dense parenchymal background .
