Alveolar adenoma of the lung: unusual diagnosis of a lesion positive on PET scan. A case report

Abstract

Abstract The authors report a clinical case of alveolar adenoma presenting as a solitary pulmonary nodule which was positive to PET and deeply located in the lung. Few cases of alveolar adenomas have been reported in literature; these lesions are considered pulmonary neoplasms with benign behaviour, usually presenting as a peripheral or subpleural coin lesion; the PET activities of such neoplasms were unknown. The present clinical case was singular for the deep location of the nodule and its tight adhesion to left inferior pulmonary vein requiring a lobectomy. In addition, alveolar adenoma PET behaviour has been reported as light positivity.
