title: Anomalous inferior vena cava associated with horseshoe kidney on multidetector computed tomography.
abstract: We evaluated the prevalence of anomalous inferior vena cava (IVC) associated with 205 patients with horseshoe kidney (HSK) and 1990 patients without HSK on multidetector computed tomography and compared prevalence between both groups. We identified anatomical variations of the IVC in 8 patients (3.9%) with HSK (1 preisthmic IVC with retrocaval ureter, 4 double IVCs, 2 left IVCs, and 1 IVC with azygos continuation) and in 12 patients (0.6%) without HSK (8 double IVCs, 3 left IVCs, and 1 IVC with azygos continuation). Anomalous IVC was significantly more frequent in patients with HSK than those without it.
