Morgagni hernia presenting with unexplained hypotension and dyspnea: A case report on successful open surgical repair

Objective: Morgagni hernias are rare congenital diaphragmatic defects, representing a small subset of all diaphragmatic hernias. They are often diagnosed incidentally or through vague, non-specific symptoms in adulthood. Case presentation: We report the case of a 75-year-old female who presented with hypotension, generalized weakness, and dyspnea. Thoracoabdominal computed tomography (CT) revealed a right-sided Morgagni hernia. She underwent open surgical repair with reduction of the herniated contents and placement of a dual mesh to reinforce the diaphragmatic defect. Her postoperative course was uneventful, and the hypotension resolved completely following surgery. Conclusion: This case highlights the importance of including diaphragmatic hernia in the differential diagnosis of unexplained hypotension and dyspnea in elderly patients. It also supports the effectiveness of mesh-reinforced open surgical repair in appropriately selected cases.
