Abstract:
Congenital cystic adenomatoid malformation (CCAM) in adolescents or adults is extremely rare. In this case study, a 17-year-old boy was admitted to our clinic for the treatment of a giant bulla in the lower lobe of the right lung. Preoperative imaging studies led to the diagnosis of cystic lung disease. The patient underwent wedge resection of the right lower lobe with VATS, and histological examination confirmed the presentation of type 1 CCAM. A thoracoscopic lobectomy was performed after the second surgery because of postoperative air leakage.Herein, we report a case of CCAM in an adolescent. VATS was a suitable procedure for the operation. Between the parenchyma-saving resection and lobectomy for CCAM, we believe that the lobectomy is the better treatment option when the extent of the disease cannot be determined clearly or it is extremely large. Therefore, strategies for deciding between parenchyma-saving resection and lobectomy for the treatment of CCAM should be developed.
