In brief: USUALLY NOT

Since aneurysms are a 'defect' in the arterial system --they can really only be seen with a contrast ct study (angiogram) or a mra (mri-angiogram).
One time i did have a patient with a leaking brain aneurysm which the effects of which were barely visible on ct but confirmed on mra--and she made it!

In brief: Not necessarily

Unless it is very large, it may not show up on a plain ct.
A ct angiogram is more sensitive.
