CTICasesEndobronchial Chicken Bone Aspiration with Actinomyces
Imaging findings
CT chest shows a hollow, curvilinear, bone-density structure (chicken rib) obstructing the right mainstem bronchus. There is associated mucous impaction, and biopsy showed granulation tissue with Actinomyces infection.
Key takeaways
Aspirated foreign bodies can present endobronchially, mimicking primary neoplasms. Chicken bones are hollow in the center and do not show significant artifact on CT. Aspiration can introduce oral flora, resulting in secondary Actinomyces infection and extensive reactive granulation tissue.
