CTICasesIncidental Systemic Arterial Supply to the Right Lower Lung
Imaging findings
CT shows a subtle, small systemic artery arising near the celiac axis, which then courses cranially to supply the right lower lung. This appears as an isolated finding without other signs of congenital anomalies like sequestration.
Key takeaways
Systemic arterial supply to lung segments can occur as an isolated, incidental finding without associated features of bronchopulmonary sequestration or other congenital anomalies. It represents a curiosity of vascular development and should be recognized to avoid misdiagnosis.
