- Asthma- No infiltrates on chest Xray.
- COPD - No infiltrates on chest Xray.
- Empyema - CXR showing features of pleural effusion, inflammatory markers on thoracocentesis.
- Pertussis - productive cough for weeks, nasopharyngeal aspirate aids in diagnosis.
- Lung abscess - CXR showing signs of lung abscess.
- Pulmonary embolus - A high degree of suspicion should be kept for pulmonary embolus. Chest X ray may be normal.
- Malignancy - CT scan and biopsy are helpful in ruling out malignancy.
- Vasculitis - Systemic manifestations of collagen vascular disease may be seen.
- Bronchiolitis obliterans with organizing pneumonia should be suspected in patients who don't respond to antibiotics treatment.
- Congestive heart failure - Bilateral pulmonary edema, involving more the lower lung fields.
- Gastroesophageal reflux disease - Normal chest Xray, symptoms worsening during night.
- Endocarditis with septic pulmonary emboli
- Upper respiratory tract infection
