“…The 2016 WHO classification separates spermatocytic tumor from seminoma. Although the cytological appearance of these two tumors are similar ( 12 ), the CEUS appearance is significantly different. The CEUS of lymphomas all showed fast forward and fast backward, except for 1 case with necrosis.…”

BackgroundUnlike young and middle-aged patients, seminoma is not common in patients with primary testicular tumors over the age of 50, so it cannot follow the general ideas and norms for diagnosing and treating testicular tumors, and its characteristics need to be considered separately.MethodsThe conventional ultrasonography and contrast-enhanced ultrasonography (CEUS) findings of primary testicular tumors in patients over 50 years old were retrospectively analyzed and compared with the pathological results to compare the diagnostic value of these two methods.ResultsOf the 13 primary testicular tumors, 8 were primary lymphomas. Conventional ultrasound of 13 cases of testicular tumors showed hypoechoic with rich blood flow, and it was difficult to identify the type accurately. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of conventional ultrasonography in diagnosing non-germ cell tumors (lymphoma and Leydig cell tumor) were 40.0%, 33.3%, 66.7%, 14.3%, and 38.5%, respectively. CEUS findings: 7 of 8 lymphomas showed uniform hyperenhancement. 2 cases of Leydig cell tumors showed uniform high enhancement. 2 cases of seminoma and 1 case of spermatocytic tumor showed heterogeneous enhancement, with necrosis in the interior. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of non-germ cell tumor diagnosis according to the non-necrotic area of CEUS were 90.0%, 100.0%, 100.0%, 75.0% and 92.3%, respectively. Compared with conventional ultrasound, the difference was statistically significant (P=0.039).ConclusionsPrimary testicular tumors in patients over 50 years old are mainly lymphoma, and CEUS is significantly different between germ cell tumors and non-germ cell tumors. Compared with conventional ultrasound, CEUS can distinguish testicular germ cell tumors from non-germ cell tumors more accurately. Preoperative ultrasonography is significant for accurate diagnosis and can guide clinical treatment.

“…Most reports do not describe sonographic findings in detail, but enlargement of the affected testicle with heterogeneity, multinodularity, hypervascularity, and cystic areas are frequently described [ 9 , [11] , [12] , [13] ]. Both tumors reported in this paper were heterogeneously echogenic with cystic areas and Doppler activity suggestive of hypervascularity.…”

Background: Different pathological types of testicular tumors are treated differently. For example, malignant germ cell tumors require radical orchiectomy, benign tumors only require mass enucleation and segmental infarction does not require treatment. Contrast-enhanced ultrasonography (CEUS) can more sensitively display tumor microvessels, thereby distinguishing between benign and malignant tumors.Methods: This was a retrospective analysis of 35 patients with primary testicular non-neoplastic and neoplastic confirmed by pathology in our hospital from February 2017 to February 2022. Conventional ultrasonography and CEUS of primary testicular non-neoplastic lesions and neoplastic lesions of different pathological types in adults were retrospectively analyzed and their diagnostic values were compared with the pathological results. Results: The sensitivity, specificity, positive predictive value, negative predictive value and accuracy rates for conventional ultrasound in the diagnosis of benign testicular tumors based on "onion skin-like" echo (epidermoid cysts) and peripheral annular blood flow were 30.8%, 100.0%, 100.0%, 71.9% and 75.0%, respectively. According to CEUS without enhancement (non-neoplastic lesions and epidermoid cysts) and uniform high enhancement with fast forward and slow backward (SLCT), the sensitivity, specificity, positive predictive value, negative predictive value and accuracy rates for diagnosing benign testicular tumors were 100.0%, 100.0%, 100.0%, 100.0% and 100.0%, respectively. Compared with conventional ultrasound, the difference was statistically significant (P=0.004).Conclusions: CEUS could accurately distinguish between benign and malignant testicular tumors and also diagnosed specific pathological types (such as testicular focal infarction, epidermoid cysts, spermatocytic tumors, SLTC and lymphoma). Different pathological types of testicular tumors had different treatment options; thus, accurate preoperative diagnosis was of great significance and could guide the selection of appropriate treatment options.
