CTICasesVariant Left Pulmonary Artery Branching
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
CT shows an unusual vascular variant where a separate branch of the left pulmonary artery comes off just after its origin in the interpericardial portion. This vessel continues adjacent to the main left pulmonary artery and gives branches to the lingula as well as the lower lobe.
Key takeaways
This is a rare, incidental anatomical vascular variant. Recognizing such variations is important to avoid misinterpretation, though its clinical significance in this specific case was not described.
