Abstract:
Objective To explore the MRI findings of testicular sex cord-stromal tumor(TSCST).Methods The MRI and clini-copathological data of 12 patients with TSCST proved by pathology were analyzed retrospectively.Results All 12 cases occurred in unilateral testicle,of which 10 cases were nodular,1 case was irregular nodular,and 1 case showed round shape.All 12 cases had clear boundaries.On T1 WI,5 cases showed homogeneous hypo-intensity,4 cases showed iso-intensity,2 cases showed inhomogeneous iso-inten-sity and hypo-intensity,and 1 case showed inhomogeneous hype-intensity.On T2 WI,7 cases were homogeneous hypo-intensity and 5 cases were inhomogeneous hypo-intensity.Diffusion weighted imaging(DWI)was performed in all 12 cases,and the apparent diffusion coefficient(ADC)was obtained.On DWI,10 cases showed homogeneous hypo-intensity,2 cases showed inhomogeneous hypo-intensity.All 12 cases showed hypo-intensity on ADC,with an average ADC value of approximately(0.89±0.09)× 10-3mm2/s.Among the MRI contrast-enhanced scans,5 cases showed progressive and obvious enhancement,1 case showed intratumoral septal enhancement,and 1 case showed obvious enhancement.Conclusion The typical MRI findings of TSCST are hypo-intensity on T2 WI,DWI,ADC,and the lesions show progressive and obvious enhancement,which are helpful for accurate preoperative diagnosis.
