Morgagni hernia (MH) is a congenital diaphragmatic hernia that is rarely seen, comprising 2-4% of diaphragmatic hernia cases. While it can remain asymptomatic, it has the potential to give rise to symptoms like cough, difficulty breathing and retrosternal pain. A chest X-ray and a computed tomography (CT) scan of the chest are sufficient for diagnosis. The only option in treatment is surgery. The objective of this study was to propose the treatment of a patient who sought our clinic due to right-sided chest pain and was diagnosed with MH, utilizing a minimally invasive surgical technique.
