Click A 46-year-old male with spontaneous portoazygos shunt and liver cirrhosis secondary to alcohol and hepatitis C. Coronal reformatted images obtained from contrast enhanced 3D VIBE (Gadobenate dimeglumine, Multihance, Bracco Diagnostics, Princeton, NJ, USA, 0.1mmol/kg) show a markedly dilated (3.9 cm in maximum diameter) azygos vein located between the liver and the aorta. (1.5T MR imaging system, Avanto, Siemens, Malvern, NJ, USA; TR=4.3, TE=1.88, matrix 320x65, FOV=41cm, slice thickness/spacing=3/0mm).
