In L1B, a lingular vein drained into the proximal inferior PV, and these two combined to form a wide common truncus to the superior PV and opened into the left atrium (Figure 10).
L1B had the second highest incidence with a rate of 25.6%, and in this variation, a lingular vein drained into the proximal inferior PV, and these two veins drained into the superior PV and opening into the left atrium.
Another finding is an independent lingular vein that joins the left atrium.
Another finding was an accessory lingular vein (Figures 2 and 3).
In our patient another finding is an orthotopic lingular vein that drains independently to the left atrium.
