Morgagni Hernia in an Adolescent With Trisomy 21: An Uncommon Presentation in a Common Syndrome

Abstract

Morgagni hernia (MH) is a rare type of congenital diaphragmatic hernia (CDH), representing 1-5% of cases, and it often presents with nonspecific or incidental findings. We report a case of a 15-year-old female with trisomy 21 who presented with abdominal distension and intermittent fever. Imaging studies, including chest radiograph and CT scan, revealed a right-sided MH containing omental and colonic structures. The patient underwent successful surgical repair. This report emphasizes the importance of considering congenital diaphragmatic anomalies in patients with genetic syndromes who present with atypical symptoms, and highlights the crucial role of thorough radiologic evaluation for accurate diagnosis and management.
