AB  - The  pulmonary  bleb  is  a  small  subpleural  collection  of  air  located  within  the  layers  of  the  visceral  pleura.  Such  lesions  usually  present  symptomatically,  heralded  by  a  spontaneous  pneumothorax.  Blebs  represent  the  coalescence  of  air  from  small  ruptures  of  terminal  alveoli  that  have  dissected  through  the  interstitium  to  form  a  small  subpleural  collection.  Lesions  that  result  in  spontaneous  pneumothorax  are  located  predominantly  in  the  apex  of  the  upper  lobe  or  the  apex  of  the  superior  segment.  Multiple  blebs  are  often  identified.  Most  patients  with  blebs  are  without  significant  underlying  lung  disease.  Pathologically,  bleb  formation  occurs  secondary  to  mechanical  stress  from  increased  intrathoracic  pressure  in  the  lung  tissue  that  is  predisposed  to  deformation  by  congenital  weakness  of  the  connective  tissue.  The  bleb  often  forms  at  the  lung  apex,  where  there  is  increased  mechanical  stress.1  Surgical  therapy  thus  is  oriented  to  the  apex  of  the  lung.
