Magnetic resonance imaging showed tumors located in the cerebellopontine angle with extracranial extension via the jugular foramen, with evident enhancement on post-contrast scan. Surgical management single-staged with the help of gamma knife radiosurgery achieved total removal.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Glossopharyngeal schwannoma is devoid of clinical symptoms and neurological signs. High resolution magnetic resonance imaging may play a key role as an accurate diagnostic tool. A favorable option of approach and appropriate planning of surgical strategy should be the goal of operation for this benign tumor.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1752-1947-2-334","type":"journal-article","created":{"date-parts":[[2008,10,28]],"date-time":"2008-10-28T07:14:22Z","timestamp":1225178062000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["A large dumbbell glossopharyngeal schwannoma involving the vagus nerve: a case report and review of the literature"],"prefix":"10.1186","volume":"2","author":[{"given":"Hongyu","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaodong","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingjie","family":"Lv","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhui","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongwei","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2008,10,27]]},"reference":[{"key":"521_CR1","first-page":"537","volume-title":"Pathology of Tumor of the Nervous System","author":"DS Russell","year":"1989","unstructured":"Russell DS, Rubinstein LJ: Pathology of Tumor of the Nervous System. 1989, Baltimore: Williams & Wilkins, 537."},{"key":"521_CR2","doi-asserted-by":"publisher","first-page":"924","DOI":"10.3171\/jns.1995.82.6.0924","volume":"82","author":"M Samii","year":"1995","unstructured":"Samii M, Babu RP, Tatagiba M, Sepehrnia A: Surgical treatment of jugular foramen schwannomas.
