Pulmonary cyst

Pulmonary cysts are cystic spaces within the lung parenchyma that have a wall that measures between 1 and 4 mm. 

The thickness of the wall is what distinguishes a cyst from a pulmonary cavity (that is defined as having a wall that is thicker than 4 mm).  A bleb or bulla has a wall that is less than 1 mm.

Pulmonary cysts can be congenital or acquired. Multiple lung cysts in a child may be associated with an underlying process although this is rare, e.g. pleuropulmonary blastomas 1.
