title: [Cystic dysplasia of the rete testis and ipsilateral kidney agenesis in children].
abstract: BACKGROUND
  Cystic dysplasia of rete testis, a rare abnormality, is often associated with renal agenesis.
  
  
  METHODS
  A 5-year-old boy was examined because he presented large scrotum. This was initially considered as hydrocele. Surgery showed a cystic dysplasia of the testis that in this patient was associated with ipsilateral renal agenesis.
  
  
  CONCLUSIONS
  This congenital abnormality, explained on the basis of embryological development, has been reported in 15 children. The testis appears cystic at surgical exploration; echography can affirm diagnosis and MRI can give specific features. A conservative attitude is proposed as this lesion is benign. Long-term follow-up is recommended for possible painful effects or growth of the lesion.
