A case of giant intradiaphragmatic bronchogenic cyst

Abstract

Abstract We present the case of a giant bronchogenic cyst (BC) that appeared just within the right diaphragm. A 51‐year‐old man was referred to our hospital with a chief complaint of pain from the lumbar area to the right shoulder. Computed tomography images showed a cystic mass measuring 18.0 × 17.5 × 12.8 cm in the right thoracic cavity. Right posterolateral thoracotomy from the eighth intercostal space was performed, and the cyst wall and diaphragm were resected together. The defect of the diaphragm was repaired using a 2‐mm‐thick Gore‐Tex™ expanded polytetrafluoroethylene patch. It is embryologically rare for a giant BC to develop within the right diaphragm. As BCs may be associated with malignant tumours or infection, complete resection of the cyst wall is required. Literature review revealed no consensus on the best surgical procedure. Therefore, it is important to consider the appropriate surgical procedure for each case.
