Diverticulum

Diverticula are out-pouchings of a hollow viscus and can be either true or false.

True diverticula
  • contains all layers of the wall of the parent organ (typically mucosa, muscular layer and serosa)
  • uncommon
  • e.g. Meckel's diverticulum
False diverticula
  • does not contain all layers (typically mucosa pushed though defect in muscular layer)
  • the vast majority of all diverticula
  • e.g. colonic diverticula

Additionally diverticula may be divided according to mechanism of formation into:
