Thank you for submitting your question. An aneurysm is an abnormal bulge/ballooning the wall of an artery. This is usually caused by a weakened area in the arterial lining.
The splenic artery supplies blood to the spleen. Over time, calcium deposits in the arterial wall weakens the lining and causes a ballooning effect. This is a calcified splenic artery aneurysm.
This type of aneurysm is found in 1% of the population. If the size is less than 2cm, risk of rupture is very low.
I hope this is helpful
