Atypical Morgagni Hernia: A Case Study Report

Introduction: Morgagni hernia is a type of congenital diaphragmatic hernia defined as a defect in the fusion of musculinization of the anterior pleuroperitoneal membrane, occurring in 1 per 3000 live births worldwide. Case Presentation: The patient was a one-year-old boy residing in the city of Kermanshah, Iran, visiting the hospital following cold signs one month before. After lung auscultation by the physician and performing chest radiography, the patient underwent further examination due to reduced lung sounds on the left side. In the chest radiography, intestine segments and stomach were shown to have entered the left side of the thoracic cavity, and the heart and mediastinum were shifted to the right. In the small intestine transit, part of the stomach fundus was observed in the lower left side of the thoracic cavity, indicative of sliding hiatal hernia. Conclusions: Intraoperative findings suggested atypical Morgagni hernia. Therefore, it is recommended that surgeons take into account rare types of hernia in their diagnoses, and perform more careful pre-operative radiography to be fully prepared.
