 | | Most lung abscesses develop after aspiration of oral secretions by patients with gingivitis or poor oral hygiene who are unconscious or obtunded from alcohol, illicit drugs, anesthesia, sedatives, or opioids. |
 | | Lung abscess less commonly complicates necrotizing pneumonia that may develop from hematogenous seeding of the lungs due to septic embolism from IV drug use or suppurative thromboembolism. |
 | | Signs of lung abscess, when present, are nonspecific and resemble those of pneumonia: decreased breath sounds indicating consolidation or effusion, temperature ≥ 39.4° C, crackles over the affected area, egophony, and dullness to percussion in the presence of effusion. |
