The left gastric, common hepatic and splenic arteries are directly originated from the aorta (normal variant).
Liver demonstrates innumerable tiny hypodensities, likely metastases, with no intrahepatic biliary radical dilatation.
Both adrenal glands are "bulky" with a tiny right sided nodule.
Cholelithiasis and unremarkable CT features of prominent CBD, portal vein, pancreas, spleen, kidneys (apart from the bilateral non-obstructive calculi) urinary bladder, pelvic gynaecological organs, and visualised opacified bowel loops.
Mixed lytic and sclerotic bony lesions are seen in the visualised bone.
Incidentally noted on this oncology follow-up CT is that the left gastric, common hepatic and splenic arteries directly arise from the aorta, which is a normal variant.
The direct aortic origin of the coeliac artery branches have the following incidences:
- left gastric artery: 2-3%
- splenic artery: <1%
- common hepatic artery: 2%
