Morgagni Hernia: A Rare Presentation in a Young Adult.

Morgagni hernia is the rarest diaphragmatic hernia, occurring in only about 2% of all cases. Despite its infrequent presentation, it poses significant morbidity once the diagnosis is missed. We present a rare case of a young adult female with no predisposing factors who experienced dyspnea and retrosternal pain with unremarkable clinical findings. A posteroanterior view of the chest roentgenogram revealed a nonspecific triangular opacity at the right cardiophrenic angle. A computed tomography (CT) scan of the thorax confirmed the suspicion of a right anteromedial diaphragmatic defect with omental herniation. Exploratory laparoscopic primary repair of the hernia orifice was performed with non-absorbable sutures. CT helps in confirming the condition, and surgical repair is recommended. Morgagni hernia can present as asymptomatic or with respiratory symptoms. There is no consensus on the type of approach, but a minimally invasive approach is being preferred even in asymptomatic cases.
