Abstract: Objective To investigate the diagnostic value of CT and MRI in basal ganglia germinoma.Methods The clinical and imaging data in 1 7 patients with basal ganglia germinoma proved pathologically or clinically were analyzed retrospectively.Results All patients were male with an age rang from 8 to 18 years old and a mean age of 10.8 years.The most common symptom was hemi-paresis.Imaging features of the lesion were as follows:① usually irregular shape(11/17,64.7%)and cystic degeneration (10/17, 58.8%)without space-occupying effect and surrounding edema (12/17,70.6%);② isointensity on conventional MRI,hyperintensi-ty on DWI and hyperdensity on CT;15 patients (15/17,88.2%)with one or more than one appearances including multiple lesions, the lesion extending into surrounding structures and Waller degeneration.Conclusion Some clinical and imaging features of the basal ganglia germinoma are characteristic,and CT and MRI shows higher diagnostic value for the disease.
