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.
