A male newborn was admitted to our Unit because of early sepsis and shock. He required antimicrobial therapy and mechanical ventilation and initially did well, although he exhibited jaundice and cholestasis. During the second week he deteriorated, with radiological opacification of the right hemithorax and pleural effusion, and did poorly in spite of antibiotical therapy and drainage of the effusion. In the third week, the X‐ray suggested some bowel loops in the right hemithorax. A right‐sided diaphragmatic hernia was confirmed by a CT‐scan, and surgery was performed with good outcome. The association of delayed‐onset right‐sided CDH following early sepsis and obstructive jaundice has not been published before, and illustrates a scarcely known form of presentation of this condition.
