3-D MR imaging of ectopia vasa deferentia.
Ectopia vasa deferentia is a complex anomaly characterized by abnormal termination of the urethral end of the vas deferens into the urinary tract due to an incompletely understood developmental error of the distal Wolffian duct. Associated anomalies of the lower gastrointestinal tract and upper urinary tract are also commonly present due to closely related embryological development. Although around 32 cases have been reported in the literature, the MR appearance of this condition has not been previously described. We report a child with high anorectal malformation who was found to have ectopia vasa deferentia, crossed fused renal ectopia and type II caudal regression syndrome on MR examination. In addition to the salient features of this entity on reconstructed MR images, the important role of 3-D MRI in establishing an unequivocal diagnosis and its potential in facilitating individually tailored management is also highlighted.
