Objective To explore the clinical application value of contrast-enhanced ultrasound in the differential diagnosis of testicular masses.Methods A total of 63 patients at the First Affiliated Hospital of Wenzhou Medical University with testicular masses from January 2014 to August 2024 were sellected.All patients underwent both conventional ultrasound and contrast-enhanced ultrasound examinations.Among them,pathological results were obtained through surgical resection in 55 cases,and 8 non-tumorous patients were diagnosed through clinical follow-up.According to the results,testicular masses were classified into neoplastic and non-neoplastic lesions.Neoplastic lesions were further divided into benign and malignant masses.The routine ultrasound parameters,serum tumor markers and ultrasound contrast parameters were analyzed.Results In the differential diagnosis between neoplastic and non-neoplastic lesions of the testis,there were significant statistical differences in the maximum diameter of the mass,blood flow grade,enhancement time,and enhancement intensity(P<0.05).In the differential diagnosis between benign and malignant testicular masses,significant statistical differences were found in mass location,maximum diameter of the mass,echo characteristics,blood flow grade indicators,enhancement time,and enhancement intensity(P<0.05).Conclusion Contrast-enhanced ultrasound may have certain reference value in the diagnosis of testicular masses.Hypo-enhancement or non-enhancement,along with slow enhancement,may be manifestations of benign lesions.
