Computed tomography and ultrasonography in the evaluation of mesonephric duct anomalies.

Three cases involving developmental anomalies of mesonephric duct derivatives were examined by computed tomography and ultrasonography. Cases included an ectopic ureter inserting into a cystic seminal vesicle, an ectopic ureterocele, and agenesis of the seminal vesicle and vas deferens. Computed tomography and ultrasonography were valuable noninvasive methods, supplementing standard radiographic techniques, for evaluating these anomalies.
