The majority of patients with WDFA and CBPB are adults with an average age of 43 years. A male predominance of 1.5:1 in CBPB and a female predominance of 3:1 in WDFA have been reported in a case series. Approximately 40% of all patients with PB are asymptomatic. Given that WDFA are generally smaller compared with CBPB, with an average size of 5.7 cm, they are more likely to be asymptomatic. Cough, chest pain, hemoptysis, dyspnea, and respiratory distress are commonly described presenting features in different case series. Fever, anorexia, fatigue, multiple chest infections, and pleural effusions have also been rarely reported. PB usually presents as a well-defined lesion on chest radiography, sometimes large enough to opacify the hemithorax, with endobronchial involvement in approximately 25% of the reported cases. They are usually limited to one lung, with an upper lobe predominance reported in some series. Pleural effusion may be present and is more likely to occur in CBPB than in WDFA.
