“…Metastases from haematogenous spread are found in the lungs, lymph nodes, liver, and retroperitoneum. Prognosis is poor with a 3-year survival rate of 60% [26]. The ultrasound appearance is a heterogeneous mass dominated by cysts involving all structures of the scrotal sac [21].…”

Clinical examination of the scrotum is difficult due to the small size of the testes and the epididymis in infants and young children, and eliciting patients' history is challenging. Therefore imaging of the scrotum in childhood bears great importance. Ultrasound is the standard imaging technique of choice providing the clinicians with a definitive diagnosis in most cases. However, in conditions of testicular torsion and epididymoorchitis--the most common differential diagnosis of scrotal pain--ultrasound findings can be inconclusive and further evaluation is required. Since there is a large overlap between paediatric and adult pathology, differences from adults in anatomy and pathology must be considered when evaluating the paediatric scrotum.

“…Others reports have shown a similar US appearance: that is, a focal nodule with multiple cystic structures. [8][9][10] In this series, there were 2 cases of a focal lesion with multiple nodules (cases 19 and 20). We think that a diffuse tumor may develop from a focal lesion.…”

“…Ultrasound (US) with a high‐frequency transducer is the primary imaging tool used for investigating testicular lesions. Most of the literature regarding testicular yolk sac tumors has been summaries of clinical therapy, and diagnoses based on US are nearly all individual case reports . To our knowledge, there has been no analysis of the US features of testicular yolk sac tumors with a large number of cases.…”

Testicular yolk sac tumors are rare, and analyses of relevant ultrasound (US) findings are limited. We retrospectively reviewed the US features of 21 pathologically verified cases (patients aged 10-64 months). Neoplasms were unilateral and solitary, occupying part (focal) or all (diffuse) of the testis. Focal lesions (14 cases) were usually solid and ovoid, with a homogeneous echo texture or multiple random anechoic spaces, and hypervascular. Diffuse neoplasms had heterogeneous echo textures; most were hypervascular. On spectral Doppler US imaging, 11 cases had a mean peak systolic velocity of 12.9 cm/s and a mean resistive index of 0.54. Ultrasound is a useful tool for imaging pediatric testes when a yolk sac tumor is suspected.

“…Y olk sac tumor (YST), also known as endodermal sinus tumor, is rare in clinical practice, but it is the most common childhood testicular malignancy. [1][2][3] The prognosis is excellent if the disease is detected and treated at an early stage-thus early diagnosis is critical. Sonographic examination is the modality of choice for diagnosis and differential diagnosis of testicular diseases.…”

Sonographic appearance of a testicular yolk sac tumor in a 2‐year‐old boy

Yolk sac tumor (YST) of testis is the most common of all childhood testicular malignancies. We report a case of testicular YST in a 2-year-old boy. The tumor appeared sonographically as an ovoid, homogeneous, well-circumscribed, isoechoic, solid testicular mass with good sound-through transmission and increased internal vascularity on color Doppler imaging. The serum alpha-fetoprotein level was 4,396 ng/ml. Pathological examination confirmed YST at at stage I. Although the sonographic appearance of YST of the testis is nonspecific, the diagnosis is achievable in clinical practice on the combination of elevated serum alphafetoprotein level and sonograms depicting a solid testicular hypervascular mass.
