That is very large for an aneurysm and should be treated.

A little over an inch in diameter. 2.54cm per inch.

Big! 3 cm is over an inch. Anything over an inch is a giant aneurysm.

It's fairly concerning. Aneurysms greater than 5 mm are followed closely. More than 1 cm is fairly serious. Please discuss this with your neurologist or neurosurgeon.

An inch is 2.54 cm. So, this is larger than an inch. You should definitely be seen by a vascular Neurosurgeon at your earliest opportunity for a review and discussion.
