Clinical and imaging analysis of testicular interstitial lesions in children / 实用放射学杂志

ABSTRACT

Objective To investigate the clinical and imaging features of testicular interstitial lesions in children.Methods The clinical and imaging data of 8 children with testicular interstitial lesions confirmed by pathology were analyzed retrospectively.Results There were 8 cases of precocious puberty,5 cases of elevated sex hormones,and 2 cases of congenital adrenal hyperplasia(CAH).The lesions were located in the unilateral testis in 6 cases,bilateral in 2 cases,single in 4 cases,and multiple in 4 cases,with diameters 3-14 mm,all of them with clear boundaries.4 cases of leydig cell hyperplasia(LCH)showed heterogeneous hypoechoic lesions,with slightly significant blood flow signal on color Doppler flow imaging(CDFI);CT showed iso-density lesions with mild enhanced after enhancement;MRI showed iso-signal on T1WI,and T2WI fat suppression were iso-signal mainly with mild enhanced after enhancement.2 cases of leydig cell tumor(LCT)showed heterogeneous hypoechoic lesions with significant blood flow signals inside and around on CDFI,CT showed iso and slightly low density with low-density necrosis,which were inhomogeneously and significantly enhanced after enhancement.2 cases of testicular adrenal rest tumor(TART)showed heterogeneous hypoechoic lesions with significant blood flow signals inside and around on CDFI;CT showed iso and slightly low density,with inhomogeneouly and significantly enhanced after enhancement;MRI showed iso-signal mainly on T1WI,and T2WI fat suppression were slightly low signal mainly with mixed signal,which were inhomogeneously and significantly enhanced after enhancement,complicated with adrenal hyperplasia.Conclusion The imaging findings of testicular interstitial lesions in children have certain characteristics,and the combination of clinical manifestations,basic diseases,laboratory and a variety of imaging examinations are helpful in improving diagnostic efficiency.
