Quiste gigante de vesícula seminal asociado con agenesia renal ipsilateral

Abstract

Cyst of the seminal vesicles represent a rare but ilustrative type of embriologic malformationwhose etiology is associated with an abnormal development of the mesonephric or Wolffian duct.Frecuently these malformations are associated with an abnormal development of the ipsilateralupper urinary tract. The initial evaluation of the majority of cases is performed with abdominal ortransrectal ultrasound. Considering the possible need of other diagnostic procedures to confirm thediagnosis, ultrasonography is safe in the majority of cases. The treatment of these urologic malformationsshould be restricted to symptomatic cases and usually consists of vesiculectomy, with ofwithout, removal of the displastic or hioplastic kidney.We present a case of a right mesonephric duct malformation with a giant seminal vesicle associatedwith ipsilateral kidney agenesis and severe oligozoospermia, that presented with sporadic episodesof hemospermia and urinary complaints
