Axial and sagittal CTA with 3D reconstruction.. Notes: (A) Axial CTA shows significant decrease in diameter of the LRV as it crosses between the aorta and the anomalous CMT. (B) Sagittal CTA shows a very acute aortomesenteric angle, with resultant compression of the LRV by SMA originating from the CMT. (C) Left anterior inferior oblique view of the NCP using 3D reconstruction of the same CTA.. Abbreviations: CMT, celiacomesenteric trunk; CTA, computed tomography-angiography; LRV, left renal vein; NCP, Nutcracker phenomenon; SMA, superior mesenteric artery.

As part of further anatomical evaluation, a CT-Angiogram (CTA) was performed, which revealed that both SMA and CeT shared the same origin (CMT) (Figure 1).
