Preferred Label : bleb;
Definition : Anatomy.—A bleb is a small gas-containing space within the visceral pleura or in the
subpleural lung, not larger than 1 cm in diameter (25). CT scans.—A bleb appears as
a thin-walled cystic air space contiguous with the pleura. Because the arbitrary (size)
distinction between a bleb and bulla is of little clinical importance, the use of
this term by radiologists is discouraged. [Fleischner Society];
