Abstract:

bronchioloalveolar carcinoma is a bronchogenic carcinoma that presents an insidious growth, arises from the walls of the distal air spaces and spreads using the alveolar septa as a stroma, preserving the lung architecture. in this work we analyze the high-resolution computed tomography of 17 patients with bronchioloalveolar carcinoma. conversely to the data presented in the literature, male preponderance (71%) and a higher frequency of association between multinodular and consolidation patterns (53%) in comparison to single nodular (12%), multinodular (12%) and consolidation (23%) patterns were observed. the most common findings were: consolidation areas (76%), air bronchogram (71%), low attenuation areas (60%), thickening of interlobular septa, ground-glass attenuation and confluent nodules (54% each), and crazy paving pattern (36%). cavitated nodules, atelectasis, halo sign and "tree in bud" pattern were observed in only one case each.
