We investigated clinical&amp;nbsp;characteristics of CPAM based on patient age at diagnosis.&amp;nbsp;Methods:&amp;nbsp;In&amp;nbsp;this retrospective study, we analyzed the medical records of 51 patients&amp;nbsp;diagnosed with CPAM at Pusan National University Hospital between&amp;nbsp;January 2000 and December 2019.&amp;nbsp;Results:&amp;nbsp;We investigated 39 children&amp;nbsp;and 12 adults. The mean age at the diagnosis of the patients was 15.9 &amp;plusmn;&amp;nbsp;14.3 years. The mean ages of children and adults at the time of diagnosis of CPAM were 6.8 &amp;plusmn; 5.8 years and 31.2 &amp;plusmn; 10.2 years, respectively.&amp;nbsp;Among the 51 patients investigated, 20 (39%) were asymptomatic&amp;nbsp;and 31 (61%) showed clinical symptoms, such as dry cough, recurrent&amp;nbsp;respiratory infections, and dyspnea at the time of diagnosis. Notably,&amp;nbsp;clinical symptoms at diagnosis were observed in 28 children (72%) and&amp;nbsp;in only 3 adults (25%) (P&amp;nbsp;= 0.006), and children were more symptomatic&amp;nbsp;than adults. Children with large cysts tended to be more symptomatic than&amp;nbsp;those with small cysts (P&amp;nbsp;&amp;lt; 0.001). Combined anomalies were detected&amp;nbsp;in 12 patients (23%). Patients with cystic lesions in the right lower lobe&amp;nbsp;of the lung showed a higher prevalence of combined anomalies (P =0.015). Surgical resection was performed in 40 patients (78%), and all&amp;nbsp;patients showed good prognosis.&amp;nbsp;Conclusion:&amp;nbsp;This study revealed that the&amp;nbsp;presence of clinical symptoms of CPAM differed between children and&amp;nbsp;adults, depending on the age at diagnosis and that patients with cysts in&amp;nbsp;the right lower lobe of the lungs tended to show a higher prevalence of combined anomalies.
