These images refer to a patient with acute liver failure due to neonatal hemochromatosis, who underwent liver transplantation (receiving a split liver graft) 20 days after birth. Seventeen days after transplantation a chest X-ray (1) showed an image of a flat right hemi-diaphragm; suspect of a hemi-paralysis of the diaphragmatic muscle. Four days later the patient underwent surgical plicature of the diaphragm, with satisfactory resolution of the complication (2).
