AB Lung  herniation  is  a  rare  cause  of  chest  pain  and  dyspnea  in  which  the  lung  parenchyma  protrudes  through  a  defect  in  the  thoracic  wall.  It  typically  occurs  due  to  a  preexisting  weakness  in  the  thoracic  wall  combined  with  an  acute  rise  in  intrathoracic  pressure  such  as  during  a  cough,  sneeze,  or  Valsalva.  Obesity,  steroid  use,  prior  injury,  and  surgery  are  risk  factors  for  herniation.  Symptoms  include  chest  pain  with  cough,  local  pain,  and  swelling  in  the  area  of  the  herniation,  which  may  vary  in  size  during  respirations.  The  deformity  is  typically  reducible.
