HRCT and pathology features of pulmonary multiple ground-glass nodules: recent progress

Pulmonary multiple groundglass nodules (GGNs) are seen common in HRCT images, which can be found in early inflammation and many small airway diseases such as respiratory bronchiolitis (RB), pulmonary langenhans cell histiocytosis (PLCH), hypersensitivity pneumonitis (HP) as well as synchronous multiple primary lung cancer (SMPLC), sarcoidosis, nodule metastatic tumors, infection, etc. HRCT and pathology features of noninfectious disease manifested as pulmonary multiple GGNs were reviewed.
