Premature newborn after umbilical venous catheter placement

US of TPNoma due to umbilical venous catheter malposition
CXR AP (above) shows the tip of the umbilical venous catheter projecting over the left portal vein. Transverse (below left) and sagittal (below right) US of the left lobe of the liver obtained 4 months later shows hyperechoic branching lesions in the liver which are felt to be calcifications in the distal branches of the portal veins due to long term direct injection of total parenteral nutrition into the distal branches of the portal veins rather than into the inferior vena cava.

The diagnosis was TPNoma due to umbilical venous catheter malposition in the left portal vein.
