Pediatric Presentation of a Celiaco-mesenteric Trunk in Association with a Pelvic Bilateral Renal Ectopia: an Undescribed Association

Background: The celiac trunk presents its normal trifurcation in the 87% of cases reported in autoptic and radiological studies. Among variants the anatomical conformation known as celiaco-mesenteric trunk has an incidence of 1-2.8%. Case Report: We hereby report a 6 years old girl who presented with recurrent abdominal pain and bilious vomiting. MRI and CT scan, performed with the diagnostic suspicion of an aorto-mesenteric compass, showed the presence of a common origin of the celiac trunk and superior mesenteric artery. In addition, images revealed also the presence of a bilateral pelvic ectopia of kidneys, with renal arteries which took origin from iliac bifurcation. The patient, two months after, was submitted to surgery, during which we found the presence of an intestinal malrotation, instead of an aorto-mesenteric compass. Conclusion: An adequate evaluation of radiologic images and the use of 3D reconstruction permits to diagnose anatomic variants of celiac-mesentric artery.
