This occurrence is exceptionally rare, but in this case it was uniquely associated with occipital neuralgia due to vascular compression of the C-2 root. Microvascular decompression was curative. Neuroradiological and surgical findings are presented and their implications discussed.<\/jats:p>","DOI":"10.3171\/jns.1993.78.4.0669","type":"journal-article","created":{"date-parts":[[2009,5,27]],"date-time":"2009-05-27T15:15:10Z","timestamp":1243437310000},"page":"669-672","source":"Crossref","is-referenced-by-count":86,"title":["Compression of the C-2 root by a rare anomalous ectatic vertebral artery"],"prefix":"10.3171","volume":"78","author":[{"given":"Rewati Raman","family":"Sharma","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harshad C.","family":"Parekh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sujit","family":"Prabhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nihal T.","family":"Gurusinghe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Bertolis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Acta Anat Nippon","first-page":"393","article-title":"[A rare abnormal case of the vertebral artery showing no passing through the foramen transversarium of the atlas.]","volume":"43","author":"Abe","year":"1968"},{"key":"b2","series-title":"Minerva Radiol","first-page":"529","article-title":"Nevralgia occipital ingravescente in un caso di ectasia dell'arteria vertebrale corrispondente.
