Abstract：Objective To investigate the clinical value of imaging in the differential diagnosis of papillary tumor of the pineal region(PTPR)and germinoma before operation.Methods The imaging data of 17 cases of PTPR and 32 cases of single pineal region germinoma confirmed by surgery and pathology in Beijing Tiantan Hospital were selected and their characteristics were summarized.Results The age of PTPR was slightly older than that of germinoma,and there was no significant difference be-tween male and female.There were significant differences in imaging features.Compared with germinoma,PTPR calcification was rare on CT,PTPR showed high signal intensity more commonly on T1WI;most of them showed mixed signal intensity on T2WI;and PTPR showed heterogeneous enhancement after enhancement.Conclusion Pineal region space occupying germinoma and PTPR have their imaging features.If the diagnosis is confirmed before operation,it has guiding significance for clinical treatment.
