GIT What do we mean by False Diverticulum

In FA , It is mentioned that diverticula termed "false in that they lack or have an attenuated musularis externa"... Any further explanation ???

I don't understand how "lack or have attenuated muscularis externa" in the same time?

I know it is only mucosa and submucosa outpouch.

and Does "attenuated" here mean "thin" ???

Thanks in advance

As you mentioned it means a small/thin part of muscularis layer (attenuated) could be involved .

True Diverticula : involve all layers of the structure, including muscularis propria
False diverticula: do not involve muscular layers. False diverticula, in the involve only the submucosa and mucosa

Google the images and compare one from another

false diverticulum is also called pulsion diverticulum & e.g. is zenker's etc

the only true one is meckel's & that contains all three layers..mucosa, submucoa, & musc. propria

so the false one has only 2 layers outpouch..

by attenuated it just means not well-developed

hope it helps..
