  1. Data are presented at diagnosis and for the last available CT scan. Observed lesions are reported according to the Fleischner Society’s Glossary of Terms for Thoracic Imaging (32). At diagnosis, ground glass opacities, interlobular thickening, intralobular lines and consolidations are the proeminent features. At last follow-up, consolidations have disappeared and fibrotic lesions are almost constant.
