AB Diverticula  of  the  esophagus  are  a  rare  entity,  with  a  prevalence  that  ranges  between  0.06%  and  4%.1,2  Esophageal  diverticula  are  classified  according  to  their  location  along  the  esophagus  (pharyngoesophageal,  midesophageal,  or  epiphrenic),  and  the  mechanism  of  formation  (pulsion  or  traction).  Most  common  diverticula  are  those  located  in  the  pharyngoesophageal  and  epiphrenic  locations.  These  are  usually  pulsion  diverticula  in  which  an  increase  of  intraluminal  pressure  leads  to  herniation  of  mucosa  and  submucosa  through  the  muscular  layer  resulting  in  a  false  diverticulum.  Mid-esophageal  diverticula  are  commonly  traction  diverticula.  These  are  much  less  frequent  and  are  the  result  of  a  focal  traction  of  all  layers  (mucosa,  submucosa,  and  musculature)  of  the  esophageal  wall  by  a  periesophageal  inflammatory  process  resulting  in  a  true  diverticulum.
