A lung abscess rupture into the bronchus typically presents with which sequence?

• A. Initial hemoptysis followed by foul-smelling purulent sputum
• B. Immediate bilateral pneumothorax
• C. Sudden wheeze with dry cough
• D. Hematemesis and melena

Answer: (A)

Rupture of a lung abscess into a bronchus creates a direct connection to the airways, so bleeding into the lumen occurs first, producing hemoptysis. As the cavity drains its purulent contents into the bronchial tree, the sputum that is expelled is typically foul-smelling and purulent due to the anaerobic organisms commonly involved. This sequence—hemoptysis followed by foul, putrid sputum—is the classic pattern seen with a rupture into the bronchus. Immediate bilateral pneumothorax would imply rupture into the pleural space rather than a bronchial drainage pattern; a sudden wheeze with dry cough points more to bronchospasm or airway irritation; hematemesis and melena suggest upper GI bleeding rather than a pulmonary process.
