Blood in a cough is hard to ignore. While lung cancer or TB tend to come to mind first, there’s a condition that gets missed far more often than it should. Aspergilloma is a fungal mass, sometimes just called a fungus ball, that settles into a cavity the lung already has, usually one left behind by old tuberculosis or a previous infection. The Aspergillus mould doesn’t go hunting for healthy tissue. It moves into the damaged space and takes up residence. What causes the bleeding is the cavity’s own blood vessels, slowly eroded from the inside.
According to Dr. George Karimundackal, a leading Thoracic Surgeon in Mumbai, “Coughing up blood after TB is one of the most common things I see. People assume the TB is back. Often it isn’t. Aspergillus has been quietly sitting in the old cavity for months, sometimes longer. The scan tells the story quickly once you know what you’re looking for. A fungal ball inside a cavity has a very particular look, and the diagnosis usually follows fast.”
Not everyone with aspergilloma knows they have it. Several patients find it entirely by accident on a scan done for something else.
The quiet ones are actually the trickier cases to manage. A simple aspergilloma can sit undisturbed for years and then bleed without any warning. Because the bleeding originates from the bronchial arteries feeding the cavity wall rather than the lung tissue itself, antifungal tablets rarely stop it. The fungal ball needs a direct solution, not more medication. Any aspergilloma diagnosis warrants a proper assessment and a surgical opinion before things escalate. The full treatment pathway is on the aspergilloma treatment page.
No single route fits every case. Aspergilloma treatment is guided by how symptomatic the patient is, how large the cavity has grown, and how much lung function they have left.
To understand the TB cavity background where these fungal balls tend to form, our piece on lung cancer vs TB is worth a read.

Aspergilloma surgery isn’t technically straightforward. Old TB cavities have thickened, adherent walls and surrounding tissue that’s already been through a lot. Each case is planned individually after careful CT review and a lung function assessment, rather than a default approach. Both VATS and open resection are part of his practice, with the choice driven by the cavity’s location and the patient’s remaining lung reserve.
He makes sure patients understand what the scans show, whether surgery or monitoring is the right next step, and what outcome they can realistically expect either way.
Coughing up blood, often mild at first, is how most patients first notice it.
Simple aspergilloma is usually cured by surgery; complex cases often need long-term antifungals.
Left untreated, chronic aspergillosis has a five-year mortality of up to 80 percent.
Surgical removal of the affected lung segment is the most definitive aspergilloma treatment.
