Which fungal infection of the lung may require surgical management such as lobectomy or cavernostomy?

• A. Aspergillosis
• B. Pneumocystis carinii
• C. Histoplasmosis
• D. Coccidioidomycosis

Answer: (A)

The main idea is that a fungal ball forming inside a pre-existing lung cavity—aspergillosis—can cause significant symptoms such as bleeding and may need surgical removal. This occurs when Aspergillus fumigatus colonizes a prior cavity (often from prior TB or other lung disease), creating a mobile fungus ball (aspergilloma). Medical therapy alone may not eliminate it or control recurrent hemoptysis, so surgeons may remove the fungus ball and surrounding involved tissue. This can be done with a cavernostomy to drain and excise the ball or, if the disease is confined to a lobe, with a lobectomy to remove the affected portion of the lung. Pneumocystis carinii pneumonia typically presents in immunocompromised patients and is treated with antimicrobial therapy rather than surgical procedures, and it does not form a removable fungus ball within a cavity. Histoplasmosis and coccidioidomycosis can involve the lungs, but surgical management like cavernostomy or lobectomy is not the standard approach for the usual presentation; they are managed mainly with antifungal therapy and supportive care, with surgery reserved for specific complications.
