The management of those patients with a radiologic CCAM who remain asymptomatic is less clear-cut. Certainly there is a risk of infection developing in a CCAM and there are also several case reports of malignancy arising in CCAM. Bronchoalveolar carcinoma pleuropulmonary blastoma rhabdomyosarcoma and bronchogenic carcinoma have all been reported 6 15 21-26 . Some authors advocate surgery in these patients to eradicate the risk of future infection or tumor. Other Fig. 4.
