CTICasesTriad of Broncholithiasis, Sequestration, and Neurogenic Tumor
Imaging findings
Chest radiographs and CT show three completely unrelated, coexisting abnormalities: 1) left upper lobe collapse and bronchial stenosis caused by a calcified broncholith; 2) a right-sided congenital hybrid lesion of bronchial atresia and intralobar sequestration characterized by a large mucus-filled bronchus, hyperlucent surrounding lung, and a large systemic arterial feeder from the celiac/SMA axis; and 3) a highly FDG-avid, stable left paraspinal mass consistent with a neurogenic tumor.
Key takeaways
This case represents a rare "triple-threat" combination of unrelated pulmonary diseases violating the law of parsimony: an infectious/inflammatory broncholith causing lobar collapse, a congenital hybrid airway-vascular anomaly (bronchial atresia/sequestration), and a benign but metabolically active neurogenic tumor.
