Pulmonary hamartomas are common benign lesions, which typically arise within the peripheral lung parenchyma and are commonly discovered on CT examination as incidental findings.
While a hamartoma is defined as disordered growth of tissues normally present within the organ, pulmonary hamartomas are clonal proliferations and therefore neoplastic.
