PVNS can arise from any synovium in the whole body and rarely affects the zygapophyseal joints of the spine. Spinal PVNS is diagnosed mostly after resection of the mass. In our case we present a 22\u2010year\u2010old male patient showing progressive spastic paraparesis with insidious onset of back pain and difficulty of walking in a relatively short period of 1 month. After gross excision of the mass, diagnosis was established through histopathology. Two years of follow\u2010up period reveals complete resolution of the patient\u2019s complaints and no recurrence on radiologic images.<\/jats:p>","DOI":"10.1155\/2013\/870324","type":"journal-article","created":{"date-parts":[[2013,9,15]],"date-time":"2013-09-15T17:04:14Z","timestamp":1379264654000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Pigmented Villonodular Synovitis of the Thoracic Vertebra Presenting with Progressive Spastic Paraparesis"],"prefix":"10.1155","volume":"2013","author":[{"given":"Mustafa","family":"Celiktas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mehmet Ozan","family":"Asik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yurdal","family":"Gezercan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahir","family":"Gulsen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,9,15]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1186\/2045-3329-3-8"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-013-1858-9"},{"key":"e_1_2_6_3_2","first-page":"859","volume-title":"Campbell\u2032s Operative Orthopaedics","author":"Carnesale P.
