title: A unique radiological pentad of mesonephric duct abnormalities in a young man presenting with testicular swelling.
abstract: Cystic dysplasia of the rete testis with associated ipsilateral renal agenesis is a very rare congenital abnormality, mainly described in the paediatric literature. In addition, the presence of a seminal vesicle cyst with ipsilateral renal agenesis is a rare but well-described entity. We present an adult who was found to have a unique pentad of mesonephric duct abnormalities on radiological imaging, including cystic dysplasia of the rete testis, seminal vesicle cyst, ipsilateral renal agenesis, partial hemitrigonal development and epididymal dilatation. We review and discuss the relevant literature of this case and discuss in detail the embryological basis for this unusual combination of findings.
