Focal area of ground glass attenuation on Left Upper Lobe. Rest of the appearances are unremarkable.
Atypical Adenomatous Hyperplasia (AAH) of the human lung has been recently implicated as a possible precursor lesion of bronchioloalveolar carcinoma (BAC). The atypical adenomatous hyperplasia-adenocarcinoma sequence has been likened to the adenoma-carcinoma sequence in the large intestine. Atypical Adenomatous Hyperplasia is the earliest lesion in stepwise development of bronchioloalveolar carcinoma.By multivariate analysis, sphericity was statistically significantly associated with atypical adenomatous hyperplasia, and internal air bronchogram with bronchioloalveolar carcinoma
