Left venous renal entrapment syndrome was observed during multidetector 64-row computer tomography and color Doppler ultrasonography in a 58-year-old Caucasian female hospitalized due to choledocholithiasis. The patient demonstrated no typical symptoms of nutcracker syndrome. The left renal vein (LRV) was compressed as it passed between the superior mesenteric artery and the right renal artery. The LRV lumen measured 1.7 × 7.8 mm (width × height) at the point of narrowing and 7.5 × 17 mm before this. Secondary to the nutcracker phenomenon, the course of left ovarian vein was winding and was significantly wider than the contralateral vessel.
