The coeliac axis arises anteriorly from

abdominal aorta just below diaphragm at the Coeliac axis
T12 level. It is a short vessel that passes
underneath the median arcuate ligament,
and then courses anteriorly or slightly

anterolaterally in the lesser sac. It is
surrounded by celiac lymph nodes and the
celiac plexus. At the upper border of the Splenic

pancreas, it divides into three branches: left artery
gastric, splenic, and common hepatic
arteries.

hepatic
artery (with

aneurysm)

Common hepatic aneurysm as
incidental finding in this patient.
This is rather rare, and may be

associated with connective tissue
(e.g. Marfan syndrome) or
rheumatological disease (e.g

polyarteritis nodosum (PAN)). They
may rupture, and treatment option
is open bypass or endovascular
stenting/ embolization.
