Background:
A diaphragmatic hernia is a defect or hole in the diaphragm through which abdominal contents can enter the chest cavity. Diaphragmatic hernias may be congenital (Morgagni hernia, Bochdalek hernia), a hiatal hernia, or acquired (iatrogenic and traumatic). Bochdalek's hernia typically occurs on the left side and rarely occurs in adults. Less than 100 cases of left Bochdalek's hernia in adults have been described in the literature. Most of them are asymptomatic.
Case report:
We report a complicated left Bochdalek hernia in a 43-year-old adult male who is a smoker. He came to the pulmonary clinic with symptoms and signs of pneumonia of the left lower lobe with persistent dyspeptic symptoms. Chest radiography revealed evidence of a left diaphragmatic hernia, which was confirmed by computed tomography of the chest and abdomen, and subsequently treated by left diaphragmatic repair via limited left thoracotomy.
Conclusion:
We report a rare case of a left Bochdalek hernia in an adult who underwent an appropriate left thoracotomy. Bochdalek hernias in adults are rare and usually asymptomatic, but when they become symptomatic, surgical intervention is required to avoid complications. BH should be considered in the differential diagnosis when radiographs suggest pneumothorax and should be treated early to avoid complications.
