It's helpful to have a full idea of what's happening.

What camera are you using? What lens?

Can you provide a photo illustrating the issue?

Vingnetting perhaps? Is the extender and lens all aligned well? Do you perhaps have a lens hood that isn't completely circular such that it's leading to vingnetting only in one corner? Or, is it really the case where vingnetting exists in all four corners and the images you're looking at make it difficult to see the effect in some corners?

happens even with the extender removed

Do you have any other lenses you can try? Very odd that this only happens in Manual Mode.  If say you switch to Av mode, take a shot (and make a note of all the settings that were used), switch to Manual and adjust to those same exact settings as used for the Av shot, this still happens?

Have you tried resetting the camera back to factory defaults?

Greetings,

Can you test with another lens?

If you are seeing this effect with no hood or extender, it might be the shutter if it follows with any lens attached.

Since all lenses, sounds like you need to contact Canon and see about having your camera repaired.  Though do first try resetting the camera just in case that clears up the issue (doubtful though).

Do you see it in the optical viewfinder? Do you see it in Live View?

Set the camera to P mode and record ISO, shutter speed and aperture. Then set the same settings in M mode.
