A Rare Variation of Retroaortic Left Renal Vein Draining into Left Common Iliac Vein

Main Article Content

Sitthichok Fangmongkol


A 24-year-old woman without underlying disease presented with right lower abdominal pain for a day. The patient’s clinical symptoms were suspected acute appendicitis and underwent multidetector computed tomography. There is diffuse enlarged appendix with diffuse wall thickening and enhancement as well as minimal surrounding fat stranding. Mild thickened peritoneum is also observed. There is no fluid collection or free air. The radiologist diagnosed acute appendicitis without complication. Incidentally, the patient was found a rare anatomical variation of the retroaortic left renal vein draining into left common iliac vein. Patient underwent appendectomy. We would like to present a characteristic imaging of the renal vein variations.
