CTICasesAccessory Connections of Superior Pulmonary Veins
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
Imaging revealed an arcade of connections between superior pulmonary veins, with one draining into the left atrium. These arcades collected blood from various pulmonary veins and coalesced before joining an inferior pulmonary vein, subsequently draining into the left atrium at a single, shared location.
Key takeaways
This case illustrates a variant of normal pulmonary venous anatomy, characterized by extensive accessory connections and arcades among the superior pulmonary veins. Unlike some meandering pulmonary veins that might have multiple central connections, this variant primarily involved the convergence of these arcades to a single central connection via an inferior pulmonary vein into the left atrium.
