Pituitary fossa aneurysm


The aneurysm went on to be coiled.

It is essential to remember to ask yourself when looking at a pituitary region mass, particularly on MRI where clot and flow-related artefacts can be confusing, "Could this be an aneurysm?", as not doing so and only finding out once a surgeon has attempted to resect the 'adenoma' can be disastrous.
