CTICasesAspergilloma with Bronchial Artery Hypertrophy
Imaging findings
Large aspergilloma with associated cavities and bronchiectasis. Contrast shows intense opacification of the pulmonary artery from systemic bronchial artery circulation (white smoke effect).
Key takeaways
This demonstrates extensive shunting and collateral flow between systemic bronchial arteries and the pulmonary circulation, often secondary to chronic inflammatory or infectious states like remote tuberculosis.
