Indian Journal of Pathology & Microbiology. 2015 Oct-Dec 58(4): 540-542.http://imsear.searo.who.int/handle/123456789/170520The 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.enDifferentiationintermediatelumbosacralmetastasispineoblastomapineocytomaspinethoracicArticle
