Abstract

Introduction: Morgagni’s hernia is the rarest of the congenital diaphragmatic defects with a reported frequency of 1% to 5.1% Morgagni hernias are more commonly seen on the right side and it occurs more commonly in females. However, most patients remain asymptomatic, and the majority of cases are discovered incidentally while investigating unrelated problems. Aim: The aim of this paper is to present a rare case of Morgagni hernia in adults and to emphasize the significant role of CT imaging in reaching the exact diagnosis of this condition. Case Report: We present a rare case of 46 years old female with an incidentally detected congenital diaphragmatic hernia on the right side. CT scan is the investigation of choice for diagnosis of Morgagni’s hernia as it allows clear visualization of the defect, and its contents. The diagnosis is established by the presence of a retrosternal mass of herniated omentum or by a transverse colon. Surgical treatment options include a transabdominal or transthoracic repair, but in the case of larger defects, a mesh may be necessary. Conclusion: Most asymptomatic cases were found in adults by chest radiography for unrelated problems. The diagnosis in the suspected case can be confirmed by a CT scan.
