Giant Morgagni hernia with multivisceral involvement: a case report of successful surgical repair in an elderly patient.

Morgagni hernia (MH) is a rare congenital diaphragmatic defect, representing 2%-4% of adult diaphragmatic hernias. It occurs through the sternocostal triangle, usually on the right side, and may remain undiagnosed because of nonspecific or absent symptoms. We report, a 75-year-old woman with hypertension and dyslipidemia presented with 3 days of progressive upper abdominal pain, dysphagia, nausea, vomiting, and poor oral intake. Examination revealed decreased breath sounds and bowel sounds over the right lung base. Chest radiography demonstrated right diaphragmatic elevation with a colonic air-fluid level. Computed tomography confirmed a large right-sided MH containing the gastric antrum, pylorus, and colon without obstruction. Surgical repair with mesh was performed, and recovery was uneventful. In conclusion, early imaging and surgical management are essential to prevent complications.
