Differential Diagnosis
Immunocompetent Hosts
- Infectious
- Necrotizing infections
- Bacterial lung abscess
- Common bacteria: anaerobes ± aerobic or microaerophilic streptococci
- Other bacteria: Staphylococcus aureus, Klebsiella pneumoniae, Enterobacterales, Pseudomonas aeruginosa, Legionella species, Haemophilus influenzae type B, Nocardia species, Actinomyces species, Burkholderia pseudomallei
- Mycobacteria: Mycobacterium tuberculosis, non-tuberculous mycobacteria
- Fungi: Aspergillus species, Coccidioides species, Histoplasma species, Blastomyces dermatitidis, Cryptococcus species, Mucorales, Pneumocystis jirovecii
- Parasites: Entamoeba histolytica, Paragonimus westermani
- Bacterial lung abscess
- Empyema with air-fluid level (i.e. hydropneumothorax)
- Septic pulmonary emboli
- Necrotizing infections
- Non-infectious
- Pulmonary embolism with infarction
- Vasculitis, including granulomatosis with polyangiitis
- Neoplasm
- Pulmonary sequestration
- Bullae or cysts with air-fluid level
- Bronchiectasis
- Cryptogenic organizing pneumonia
- Sarcoidosis
- Rheumatoid nodules
- Pulmonary Langerhans histiocytosis
- Foreign body aspiration
Immunocompromised Hosts
- Common
- Bacteria: Pseudomonas aeruginosa, Enterobacterales, Nocardia species, anaerobes and microaerophilic streptococci, Staphylococcus aureus
- Mycobacteria: Mycobacterium tuberculosis, Mycobacterium kansasii
- Fungi: Cryptococcus species, Aspergillus species, Histoplasma capsulatum
- Less common
- Bacteria: Rhodococcus equi, Legionella species
- Mycobacteria: Mycobacterium avium complex, non-tuberculous mycobacteria
- Fungi: Mucorales, Blastomyces dermatitidis, Pneumocystis jirovecii
