Abstract:
Objective To discuss the imaging features of germ cell tumors on CT and MRI.Methods Preoperative CT and MRI data of 11 pathologically proved germ cell tumors were analyzed retrospectively.A total of 11 cases were enrolled in the study,4 cases received plain and contrast-enhanced CT scan,1 received plain and contrast-enhanced MRI scan,and 6 received both CT and MRI scan.Results Histological examinations revealed 11 testicular neoplasms,among which 4 cases were seminoma,1 was embryonal carcinoma,1 was immature teratoma,3 were mixed germ cell tumors,1 was spindle cell rhabdomyosarcoma and 1 was carcinoid.Most germ cell tumors were iso density or low density with or without clear boundary,mild to moderate enhancement on CT scan.On MRI scan,most germ cell tumors showed iso-hyper intensity on T1WI,hypointensity,isointensity or hyperintensity on T2 WI,heterogeneous mild to moderate enhancement,high signal intensity on DWI,and low or high signal intensity on ADC.Conclusion Typical testicular germ cell tumor imaging performance has a certain specificity,but the atypical germ cell tumor lacks specificity.So the final diagnosis still depends on the pathology.
