title: Functional ureteral obstruction due to complex pelvic venous anomaly.
abstract: Venous anomalies are rare causes of ureteral obstruction. We report the case of a 31-year-old woman with obstruction of the right distal ureter by a complex pelvic venous anomaly. Beside benign and malignant lesions of the retroperitoneum, venous anomalies should also be considered in the differential diagnosis of extrinsic ureteral obstruction. Due to its abilities of three-dimensional visualization, multi-detector row computed tomography is helpful in the depiction of venous anomalies.
