A 13-year-old was referred for scrotal US for painlessenlargement of the right testicle. US showed multipledilated fluid-filled spaces in the rete testis with compressednormal testicular parenchyma (Fig. 1). VATER associationhad been diagnosed with an absent right kidney.
Cystic dysplasia of the rete testis is a rare entity with only
15 cases reported in the literature up to 2001 [1]. Congenitalcystic dysplasia of the rete testis is a consequence of an earlyinsult involving the development of the mesonephric duct.This explains the almost universal association with renal
agenesis or multicystic dysplastic kidney on the same side,and also helps differentiate it from a malignant tumor.
Confusion exists between congenital cystic dysplasia ofthe rete testis and the unrelated but similarly namedincidental finding in elderly men called tubular ectasia ofthe mediastinum testis or ectasia of the rete testis [2]. This
is often bilateral and not associated with testicular enlarge-ment or renal anomalies.
