Simple intratesticular cysts in children: preoperative sonographic diagnosis and histological correlation

Abstract

Our findings appear to support the hypothesis that these cysts could correspond to mesothelial inclusions. Sonographically, differential diagnosis should include mainly epidermoid cysts of the testis, which are mostly cystic but characteristically contain some echoes within them, in contrast to simple cysts and cysts of the tunica albuginea, which lie outside the testicular parenchyma.

Testicular and paratesticular tumors and tumor-like lesions in the first 2 decades

“…238 In one case most of the testis was replaced. On gross examination all were simple, single cysts that contained clear, serous fluid.…”

“…Because of their characteristic ultrasonographic appearance, conservative, testicular-sparing surgical treatment is possible. 238 …”

Benign cystic lesions in the testis of children

“…In adults, they are usually small and detected as incidental findings [15]; in infants, they may cause an increase of scrotal size [16,17]. Unlike most other cystic testicular lesions, they are usually not palpable, as they are often deeply embedded within the testicular parenchyma.…”

“…The surrounding rim is echogenic and is composed of compromised testicular parenchyma. Characteristically, there is a dorsal sound reinforcement [17].…”

Paediatric ultrasound. Part 2: Other applications

“…These cysts could correspond to mesothelial inclusions. Sonographically, differential diagnosis should primarily include epidermoid cysts of the testis, which are mostly cystic but characteristically contain some echoes within them, in contrast to simple cysts and cysts of the tunica albuginea, which lie outside the testicular parenchyma [109]. Ultrasound may detect small amounts of scrotal adrenal rest tissue in congenital adrenal hyperplasia.…”
