Low-dose chest computed tomography (LDCT). a 2 years before admission, numerous calcified nodular infiltrations were present in whole lung fields. Minimal subpleural septal thickening with reticulations in the right middle lobe (RML) and both lower lobes (BLLs) were observed. Lymph node enlargements with calcifications were found in the mediastinum, hilum, interlobar, and lobar regions. b Upon admission, multifocal patchy areas of consolidation were found in both lungs suggesting extensive pneumonia. Furthermore, diffuse ground glass opacity was noted in both lungs suggesting pulmonary edema with or without hemorrhage
