Introduction:
Bochdalek hernias are a type of diaphragm hernia. Almost all occur in the neonatal period, only 5% of these hernias occurring in adults. We here present a rare case of adult Bochdalek hernia incarcerated in the extra-pleural space.
Presentation of case:
An asymptomatic 51-year-old man was admitted to our hospital for a detailed examination after an abnormality had been detected on a chest radiograph. Chest computed tomography (CT) examination revealed findings consistent with a left Bochdalek hernia, which we repaied surgically. Intraoperatively, retroperitoneal fatty tissue was found to be incarcerated in the extra-pleural space. Thus, surgical repair required dissection of the parietal pleura and excision of the incarcerated fatty tissues.
Discussion:
The incarceration of the Bochdalek hernia in the extra-pleural space could not be identified on a preoperative chest CT examination. To the best of our knowledge, no reports of incarceration of a Bochdalek hernia in the extra-pleural space have been published; thus, this phenomenon is extremely rare.
Conclusion:
Surgical treatment of a Bochdalek hernia incarcerated in the extra-pleural space requires dissection of the parietal pleura and repair via a transthoracic approach.
