Diverticula are outpouchings of a hollow viscus and can be either true or false.

Diverticula is the correct Latin plural form. 'Diverticuli' and 'diverticulae' are erroneous and should not be used. 

True diverticula
  • contains all layers of the wall of the parent organ (typically mucosa, muscular layer and serosa)
  • uncommon
  • e.g. Meckel 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 diverticulum

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

Pulsion diverticula
Traction diverticula
