Magnetic resonance imaging revealed a pineal tumor that induced obstructive hydrocephalus. A biopsy and endoscopic third ventriculostomy were performed. Histological diagnosis revealed a grade II PPTID. Two months later, the tumor was removed via craniotomy because the postoperative Gamma Knife surgery was ineffective. Histological diagnosis confirmed PPTID, although the grade was revised from II to III. Postoperative adjuvant therapy was not performed, because the lesion had been irradiated and gross total tumor removal was achieved. She has had no recurrence in 13 years. However, pain around the anus newly appeared. Magnetic resonance imaging of the spine revealed a solid lesion in the lumbosacral spine. The lesion was subtotally resected, and histological diagnosis revealed grade III PPTID. Postoperative radiotherapy was performed, and she had no recurrence 1 year after radiotherapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Remote dissemination of PPTID can occur several years after the initial resection.
