1. Lung cancer has variable imaging manifestations including nodules, masses, focal or diffuse ground-glass opacities and consolidation 2. A variety of disease entities mimic lung cancer and cause false-positive interpretation of imaging studies 3. Awareness of lung cancer mimics help radiologists provide appropriate differential considerations and guide further diagnostic work-up

Review variable imaging appearance of lung cancer      o Nodule/Mass      o Endobronchial lesion      o Consolidation, ground-glass opacity Interactive case-based quiz questions to illustrate lung cancer mimics and distinguishing features, if any      o Neoplasm other than lung cancer          Pulmonary lymphoma          Carcinoid tumor          Metastasis          Sarcoma      o  Infection          Pneumonia          Abscess          Mycobacterial infection          Fungal infection      o  Non-infectious benign entities          Hamartoma          Amyloidosis          Sarcoidosis          Necrobiotic Nodule          Organizing pneumonia          Rounded atelectasis          Lipoid Pneumonia          Granulomatosis with polyangiitis
