title: Pronounced cystic transformation of the Rete testis. MRI appearance.
abstract: Cystic transformation of the rete testis is a little-known partial or complete obstruction of the spermatozoa-containing secretion of the head of the epididymis. Depending on its severity, either ectasia or a cystic transformation occurs, which spreads to the network of convoluted seminiferous tubules in the mediastinum testis. Findings in contrast-enhanced MRI examinations are characteristic and may help to differentiate this benign entity from malignant neoplasia. The authors present two pronounced cases in different stages, documenting the broad spectrum of possible involvement.
