Abstract

Authors have continued radiological research for the application of three-dimensional computed tomography (3D-CT) using Synapse Vincent, Japan. The patient was a 51-year-old female with bilateral flank pain. For plain and contrasted CT scan, artery and portal late phases showed possible nutcracker syndrome (NCS) or renal vein entrapment syndrome. 3D-CT images suggested that i) there was a clear relationship between the superior mesenteric artery (SMA) and inferior vena cava (IVC), ii) a collateral vessel for the left ovarian vein (LOV), and iii) compression of the small intestine on the left renal vein (LRV). Thus, her pathophysiological mechanism was probably supposed by the 3D-CT reconstruction technique method.
