Clinical value of contrast-enhanced ultrasound in the differential diagnosis of testicular tumors and tumor-like lesions

Objective To analyze the characteristics of conventional ultrasound and contrast-enhanced ultrasound(CEUS)in adult testicular tumors and tumor-like lesions,and to explore the value of contrast-enhanced ultrasound in their differential diagnosis.Methods Conventional ultrasound and CEUS data of patients with testicular tumor and tumor-like lesions confirmed by surgery and pathology(26 cases in testicular tumor group and 14 cases in tumor-like lesions group)were retrospectively analyzed,the imaging features of the two diseases was compared and the diagnostic efficacy of CEUS in two diseases was analyzed.Results There were statistically significant differences in lesion size,morphology and echo between testicular tumor group and tumor-like lesion group(all P<0.05).There were statistically significant differences in enhancement intensity,enhancement shape,enhancement mode and“pseud-capsule”sign between two groups(all P<0.05).The sensitivity,specificity,and accuracy of conventional ultrasound in the diagnosis of testicular tumors were 88.5%,64.3%,and 80.0%.The sensitivity,specificity,and accuracy of CEUS in the diagnosis of testicular tumors were 100%,92.9%,and 97.5%,there was no significant difference in the diagnostic efficacy between the two methods.Conclusion The feature of CEUS is helpful for the differential diagnosis of different testicular tumors and tumor-like lesions,which has important clinical value.
