Traumatic diaphragmatic rupture is a rare clinic pathological entity and a missed diagnosis. Diaphragmatic injury may result in the development of delayed herniation and strangulation of abdominal organs into the thoracic cavity. Spontaneous (effort or delayed) rupture of diaphragm is rarely seen with the incidence of approx. 1% without obvious blunt trauma of abdomen. This poses a great difficulty to the surgeons and radiologists to diagnose. Very easily the diagnosis is missed or confused with pneumothorax or hydro pneumothorax. The Spontaneous rupture of Right sided diaphragm is very rare in comparison to left sided rupture. Diaphragmatic hernia without trauma in adults is a very rare entity. The reported cases of Right sided diaphragmatic hernia in literature so far is only less than 20. We report 2 cases of Right sided spontaneous delayed diaphragmatic hernia, who presented in our out patients clinic with the chief complaint of breathlessness on exertion. In both the cases, the defect was repaired with primary closure and reinforced with marlex mesh.
