Cystic dysplasia of the testis: a rare cause of painless hemiscrotal enlargement in childhood

Abstract

Cystic dysplasia of the testis is a rare, benign cause of painless hemiscrotal enlargement in children. We present two cases of cystic dysplasia of the testis presenting with scrotal enlargement. The diagnosis was based on its specific sonographic findings and on the coexistence of a multicystic dysplastic kidney in one case.

A Case of Cystic Dysplasia of the Rete Testis in a 17-Months-Old Boy

“…Sonography is recognized as the imaging method of choice for the evaluation of the nature of testicular abnormalities as well as for the followup of untreated forms [1, 10, 11]. In CTD, the sonographic examination of the testis reveals multiple small cysts located in the mediastinum, whereas the surrounding testicular tissue appears to be normal, but compressed [4, 10].…”

“…In CTD, the sonographic examination of the testis reveals multiple small cysts located in the mediastinum, whereas the surrounding testicular tissue appears to be normal, but compressed [4, 10]. The cysts range in size from microscopic to several millimetres and it may be diffused, involving the whole parenchyma or focal [11].…”

“…When the cysts are tiny, they may be sonographically demonstrated as echogenic foci mimicking testicular microlithiasis, a potential premalignant condition, though intraluminal calcification has been found in association to CDT [4, 11]. High frequency transducer is suggested to be of aid in the differential diagnosis of these entities [10]. …”

“…The differential diagnosis of cystic testicular lesions in children include epidermoid, dermoid, inflammatory, posttraumatic, or congenital testicular cysts [10]. Cystic degeneration after torsion, prepubertal teratoma, juvenile granulosa cell tumor, as well as testicular cystic lymphangioma, although rare in childhood, should also be considered [14].…”
