Common celio-mesentric renal trunk: An extremely rare anatomic variant

Anatomic variations in the branches of abdominal aorta are very common. Among them, the most common variations are those involving the renal arteries. We report the case of a 9 year old boy with complaints of intermittent abdominal pain, bilateral lower limb claudication & hypertension that was referred for evaluation. An extremely rare variation in the origins of visceral and renal arteries was noted in this patient with the abdominal aorta giving rise to a common trunk at T12-L1 level which further branched into celiac artery, superior mesenteric artery and both renal arteries. The native aorta distal to the origin of this common trunk showed circumferential wall thickening with decreased luminal diameter suggestive of aorto-arteritis.
