Abstract

Approximately 60% to 90% of cases of congenital diaphragmatic hernia (CDH) are detected prenatally by sonography or MRI depending on the center. The CDH is suspected usually if the stomach bubble is not observed in its normal intra-abdominal location. The fetal chest should be viewed in the true transverse plane, and landmarks such as the inferior margin of the scapula should be used to identify the abdominal viscera in the chest. Abdominal viscera that are seen cephalad to the inferior margin of the scapula or at the same level of the four-chamber view of the heart are herniated, confirming a diagnosis of CDH. The herniated abdominal viscera associated with a left-sided CDH may be the easiest to detect. The fluid-filled stomach and small bowel contrast strikingly with the more echogenic fetal lung. The abdominal viscera such as the fluid-filled stomach are barely confused with the pleural effusion. We experienced a case improved fetal pleural effusion revealed as CDH and report this uncommon case to the journey of the diagnosis. The fetal pleural effusion may be the early sign of CDH.
