title: Clustered pulmonary nodules: highly suggestive of benign disease.
abstract: Thirty-one adult patients with a cluster of small, noncalcified, pulmonary nodules identified on chest computed tomography (CT) examinations were studied retrospectively. Pathology revealed an infectious/inflammatory etiology in all cases in which a surgical resection of the involved lung was performed. None of the patients in our study group showed evidence of malignancy in the region of a cluster of pulmonary nodules over the follow-up period. The authors conclude that an isolated cluster of small pulmonary nodules is strongly suggestive of benign disease. Although exceptions may rarely occur, most cases represent incidental infectious or inflammatory disease.
