Which symptom is commonly associated with a lung abscess?

• A. Putrid sputum
• B. Productive non-putrid sputum
• C. Hemoptysis only
• D. Chest tightness

Answer: (A)

Lung abscesses commonly produce foul-smelling, putrid sputum due to anaerobic infection and tissue necrosis in the cavity. The odor and purulence come from sulfur-containing compounds released by anaerobic bacteria such as Bacteroides, Fusobacterium, and Peptostreptococcus that often seed aspiration-related infections. While patients can have fever, cough, and night sweats, the standout symptom linking to an abscess is this putrid sputum. Other findings like productive non-putrid sputum are more typical of uncomplicated bronchitis or typical pneumonia, hemoptysis can occur but is not the defining feature, and chest tightness is nonspecific.
