CTICasesBronchomammary Fistula post-RFA
Imaging findings
CT chest in a patient who underwent radiofrequency ablation (RFA) for a central right lung tumor shows a massive air collection within the right breast tissue, communicating directly with a tract (fistula) extending from the right mainstem bronchus.
Key takeaways
Radiofrequency ablation of central lung lesions carries a risk of thermal injury to major airways. Excessive energy delivery or proximity to the chest wall can create complex bronchocutaneous or bronchomammary fistulas that are highly susceptible to recurrent infection and difficult to close surgically.
