Clinical analysis of Leydig cell tumors by contrast-enhanced ultrasound performance

Objective To investigate the diagnostic value and clinical diagnosis experience of contrast-enhanced ultrasound(CEUS)of Leydig cell tumors.Methods CEUS performance,clinical data and ultrasound diagnostic analysis of one case of Leydig cell tumor were analyzed.Results According to the clinical manifestations and the related inspections,the indications for surgery were clear.During the operation,a section was frozen to consider the source of the sex cord tumor,the nature of which was indefinable.The right testis was radically resected.Leydig cell tumor was diagnosed by postoperative analayis of the parrafin sections and immunohistochemistry.No recurrence or metastasis was seen after six months of follow-up.Conclusion Leydig cell tumor is a relatively rare testicular tumor and has a tendency to become malignant.The reports of CEUS diagnosis of Leydig cell tumors are rare.There are no specific clinical manifestations and the relevant laboratory parameters are normal,resulting in Leydig cell tumors being confused with other malignant testicular tumors.Its preoperative diagnosis is difficult and the definitive diagnosis still relies on histopathological examination.
