CTICasesLeft Pulmonary Isomerism
Imaging findings
Chest CT and coronal reformats show two morphologic left lungs with hyparterial bronchus-pulmonary artery relationships bilaterally, an accessory bronchus supplying the right apex, and absence of the horizontal fissure.
Key takeaways
Left pulmonary isomerism (bilateral left lungs) is a congenital anomaly characterized by hyparterial bronchi on both sides and two-lobed lungs. It can be associated with accessory airway branching patterns.
