Which is a potential cause of hemothorax?

• A. Trauma
• B. Pneumonia
• C. Asthma
• D. Pulmonary fibrosis

Answer: (A)

Hemothorax is blood collecting in the pleural space. Trauma is a classic and direct cause because blunt or penetrating chest injuries can tear intercostal vessels or lung tissue, releasing blood into the pleural cavity and impairing lung expansion. The other conditions listed aren’t typically associated with blood in the pleural space: pneumonia can cause a pleural effusion or empyema (fluid may be infected or purulent, not frankly bloody); asthma involves airway hyperreactivity and doesn’t injury the chest structures to bleed into the pleural space; pulmonary fibrosis is scarring of the lung tissue and likewise does not produce hemothorax.
