XXXX of the rete testis: clinical and radiographic features.

@entity1 @entity4122 @entity12844 @entity158 @entity1062 @entity169
PURPOSE: @entity4122 of the rete testis is a rare condition that may be incidentally noted on scrotal ultrasonography. This benign condition has a typical appearance of a collection of small anechoic structures in the confluence of the mediastinum testis. The main significance of this condition is that it must be differentiated from @entity1062 . We reviewed the experience with this condition at our institution. MATERIALS AND METHODS: A retrospective review was performed to identify all sonograms showing ectatic rete testis performed from 1998 through February 2002. A departmental database was used to identify all scrotal sonograms from this period showing ectasia of the rete testis and clinical correlation was done. These examinations were then reviewed by a single radiologist. RESULTS: We identified 13 cases in the last 4 years. Ultrasound was most commonly performed for a testicular or scrotal mass, or @entity158 . Median @entity1 age was 65 years. All except 1 @entity1 had an underlying condition, including vasectomy, @entity12844 /spermatocele or @entity169 , that could cause epididymal or efferent duct obstruction. No @entity1 had a solid testicular mass. CONCLUSIONS: Based on clinical and sonographic criteria the diagnosis of @entity4122 of the rete testis can be made without histological confirmation. Identifying this entity and its associated conditions avoids the need for biopsy or orchiectomy.
