Imaging in adult presentation of congenital intrapericardial diaphragmatic hernia

Intrapericardial diaphragmatic hernia is a rare non-hiatal diaphragmatic hernia that occurs due to a traumatic or congenital defect in the pericardial portion of the central tendon of the diaphragm. It is characterized by the herniation of abdominal viscera into the pericardial cavity. A high index of suspicion and appropriate radiological investigations are key to diagnosis, as this condition can clinically mimic other gastrointestinal or cardiorespiratory conditions.
