Abstract：Pineal parenchymal tumors of intermediate differentiation(PPTID)are a kind of rare moderately malignant tumors,and their imaging manifestations are sometimes difficult to differentiate.This paper reports a case of a middle-aged male with a space-occupying lesion in the pineal region.The imaging examination indicated an embryonic tumor.Eventually,a partial resection of the space-occupying lesion in the pineal region combined with biopsy was carried out,and the postoperative pathological diagnosis was PPTID.Postoperative radiotherapy was administered,and the patient was followed up for 12 months without recurrence.The imaging manifestations of PPTID have certain characteristics,but the final diagnosis requires a combination of pathological examination.Surgical resection is the preferred treatment method,and postoperative radiotherapy and chemotherapy can improve the prognosis of patients with PPTID.
