The 2007 World Health Organization classification of tumors of the central nervous system identified "pineal parenchymal tumor of intermediate differentiation" (PPTID) as a new pineal parenchymal neoplasm, located between pineocytoma and pineoblastoma as grade II or III. Because of the small number of reported cases, the classification of PPT is still a matter of controversy. We report a case of PPTID. A 25-year-old female patient was admitted to hospital with complaints of a headache, nausea, vomiting since 1-year. Computed tomography/magnetic resonance imaging of the brain showed well-defined, mildly enhancing lesion in the region of the pineal gland with areas of calcification. The tumor was excised. After 3 years, she presented with metastasis in thoracic and lumbosacral spinal region. This is a rare event.
2007年世界卫生组织中枢神经系统肿瘤分类将“中间分化型松果体实质肿瘤”（PPTID）确定为一种新的松果体实质肿瘤，介于松果体细胞瘤和松果体母细胞瘤之间，为Ⅱ级或Ⅲ级。由于报告的病例数量较少，PPT的分类仍存在争议。我们报告一例PPTID病例。一名25岁女性患者因头痛、恶心、呕吐1年入院。脑部计算机断层扫描/磁共振成像显示松果体区域有边界清晰、轻度强化的病变，并伴有钙化区域。肿瘤被切除。3年后，她出现胸段和腰骶段脊柱转移。这是一个罕见的情况。
