ABSTRACT
INTRODUCTION: Congenital diaphragmatic hernia (CDH) presenting after 30 days of life is unusual and has a variant pattern of presentation. PRESENTATION OF CASE: We present a death case occurred to a 34-days-old infant. The infant arrived to our emergency department in cardiac arrest after having suffered from intermittent acute abdominal pain. Autopsy confirmed the presence of a right CDH, with herniation of the right lobe of the liver into the thorax. DISCUSSION: Most of the cases of CDH are diagnosed prenatally or in the neonatal period. However, some patients do not develop symptoms until after the neonatal period. The relevance of our case is the co-existence of right CDH and important hypotrophy of the right lobe of the liver. CONCLUSIONS: Evidence of this phenomenon represents an absolute novelty in the extant scientific literature. Even if rare, we suggest to suspect the presence of CDH in fetus with disparity in right and left liver lobe at prenatal ultrasound.
