While predilection sites are the posterior mediastinum and retroperitoneal cavity, ganglioneuroma originating from the dorsal root ganglion is very rare. Here the authors report a case with C2 dorsal root ganglion-derived ganglioneuroma with some literature review.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 45-year-old male patient complained of persistent right-side throbbing occipital headache for more than a year. Magnetic resonance imaging (MRI) of the cervical spine revealed a dumbbell-shaped intradural extramedullary tumor from the C2 posterior surface of the odontoid to right C1\u20132 intervertebral foramen with high T2- and low T1-weighted signal intensities. The tumor displayed homogeneous contrast enhancement by MRI. The authors suspected schwannoma and performed a tumorectomy for both diagnosis and treatment purposes. Intraoperative findings showed that the tumor originated from the dorsal root ganglion, and pathological examination revealed ganglioneuroma. Immediately after the tumorectomy, the throbbing occipital headache disappeared and the patient was discharged from the hospital without major complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Although ganglioneuroma derived from the dorsal root ganglion is very rare, a differential diagnosis of the ganglioneuroma should be made, when schwannoma is suspected.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case22456","type":"journal-article","created":{"date-parts":[[2023,1,16]],"date-time":"2023-01-16T03:08:52Z","timestamp":1673838532000},"source":"Crossref","is-referenced-by-count":3,"title":["Cervical ganglioneuroma arising from the dorsal root ganglion: illustrative case"],"prefix":"10.3171","volume":"5","author":[{"given":"Shinya","family":"Torimaki","sequence":"first","affiliation":[{"name":"Shin-Aikai Spine Center, Katano Hospital, Katano City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuhiro","family":"Sasaki","sequence":"additional","affiliation":[{"name":"Shin-Aikai Spine Center, Katano Hospital, Katano City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiro","family":"Ohara","sequence":"additional","affiliation":[{"name":"Shin-Aikai Spine Center, Katano Hospital, Katano City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeo","family":"Ueda","sequence":"additional","affiliation":[{"name":"Shin-Aikai Spine Center, Katano Hospital, Katano City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minoru","family":"Hoshimaru","sequence":"additional","affiliation":[{"name":"Shin-Aikai Spine Center, Katano Hospital, Katano City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"6","key":"b1","series-title":"J Neurosurg Spine","first-page":"587","article-title":"Spinal dumbbell tumors: an analysis of a series of 118 cases","volume":"7","author":"Ozawa H","year":"2007","unstructured":"Ozawa H, Kokubun S, Aizawa T, Hoshikawa T, Kawahara C.
