Pulmonary venous varix

Pulmonary vein varix (PVV) also sometimes termed a pulmonary venous aneurysm refers to a localised aneurysmal dilatation of a pulmonary vein. As it involves a venous structure, the former term is usually considered more appropriate. They are rare and may be congenital or acquired.

Clinical presentation

It is usually asymptomatic.


While they can occur anywhere in the chest, they are thought to typically occur at the confluences of the veins adjacent to the left atrium 3.

They are sometimes classified into three morphological types by some authors:

  • saccular type: considered most common 9
  • tortuous type
  • confluent type

Radiographic features
