CTICasesTransbronchial Biopsy Sites ("Bronch Bites") on CT
Imaging findings
Chest CT in a lung transplant recipient performed twenty-four hours after a bronchoscopy reveals small, linear, non-cavitary gas-containing lucencies near the pleural surface, most prominently in the lateral segment of the middle lobe. These findings correspond to the sites of transbronchial biopsy.
Key takeaways
Post-procedural CT scans following transbronchial biopsies can show tiny, peripheral gas-filled defects, often colloquially called 'bronch bites.' These benign, transient post-procedural findings are typically located in the middle or lower lobes and should not be mistaken for cavitary infections, abscesses, or lung necrosis.
