# A unique posterior nutcracker syndrome combined with Wilkie syndrome: A singular case

## TL;DR

This paper reports a rare case of a left renal vein variant combined with another rare syndrome involving the duodenum.

## Contribution

The paper presents a unique co-occurrence of two rare vascular anomalies in a single patient.

## Key findings

- A left renal vein was found compressed between the left iliac artery and vertebral bodies.
- The patient also had superior mesenteric artery syndrome, where the duodenum was compressed between the aorta and the superior mesenteric artery.
- CE-CT was effective in diagnosing these vascular anomalies.

## Abstract

Left renal vein variants are not commonly observed in the general population. Usually, the renal vein runs in front of the aorta before entering the inferior vena cava, while the most common variants include the presence of a circumaortic or retroaortic renal vein. However, when present, left venal rein variants are important to recognize due to their potential clinical and surgical relevance. In this regard, CE-CT is an instrument with high sensitivity and specificity in detecting vascular anomalies and can certainly help diagnose. In this article, we present a unique case of a left venal rein compressed between the left iliac artery and vertebral bodies associated with the presence of a superior mesenteric artery Syndrome, another rare entity that occurs when the duodenum is compressed between the aorta and the superior mesenteric artery.
