Possible differential diagnosis of lung diseases in the current case history

Possible diagnosis	Clinical symptoms	Radiological findings
Interstitial lung disease	Dyspnea, non-productive cough, malaise, fatigue, weight loss	X-ray – consolidation, fibrosis; HRCT – consolidation, fibrosis, ground glass partial alveolar filing, reticulonodular pattern.
Tuberculosis	Productive cough, malaise, fatigue, weight loss, night sweats, hemoptysis	X-ray – infiltration, cavitation, nodularity, hilar/paratracheal lymphadenopathy, pleural effusion, atelectasis; HRCT – infiltration, granulomas and tree-in-bud appearance
Amiodarone-induced interstitial lung disease	Progressive shortness of breath (dyspnea), non-productive cough, malaise, fever, pleuritic chest pain	X-ray – consolidation, fibrosis; HRCT – diffuse interstitial pneumonitis with fibrosis and ‘ground-glass’ opacities, consolidation
Vasculitis	Fever, weight-loss, fatigue, evidence of multisystem involvement, rashes	X-ray – pneumonia-like x-ray picture; HRCT – bilateral perihilar or peripheral ground-glass opacities, pulmonary haemorrhage
Wegener’s granulomatosis	Necrotizing granulomatous lesions of respiratory tract, ulcers, malaise, fatigue, weight loss	HRCT – perihilar or peripherical ground-glass opacities, pulmonary haemorrhage, necrotizing granulomas
Lung tumor	Dyspnea, non-productive cough, malaise, fatigue, weight loss, hemoptysis	X-ray – nodule or mass with hilar enlargement, lobulated hilar mass, atelectasis; HRCT – solid or mixed pulmonary nodules or mass, atelectasis, lymphadenopathy
Bacterial lung infections	Fever, chills, productive cough, dyspnea, pleuritic chest pain, fatigue	X-ray – consolidation of the lobe, dense opacities, pneumothorax, hydrothorax; HRCT – centrilobular nodules, tree-in-bud pattern, pleural-based consolidation
