Suspected aneurysm on pituitary. Tortuosity of vessels noted in the CTA. What is it?

Hi, I had a CTA because on the MRI , they thought there was something on my Pituitarry, The MRA showed something more suspecting of an aneurysm so they did a CTA. On the results they rulled out the aneurysm but said there vessels in the let P1 which were torturisity and most likely resembled the aneurysm. Can you explain the torturisity. I have heard this can cause stroke if not repaired.

Thank you for posting your query.

Tortuousity of the blood vessel refers to mild abnormal dilatation of the blood vessel, however, it is not similar to an aneurysm. An aneurysm is an abnormal out-pouching of the artery (a ballon like dilatation).

An aneurysm has a higher risk of rupture and causing brain haemorrhage (bleeding in the brain).

Tortuous vessel may predispose to a stroke, as blood flow may be sluggish through a tortuous vessel leading to thrombosis (clot formation). However, this risk is very small.

Wishing you good health,
