Notably, the tumor compressed both the spinal cord and the right vertebral artery. At the end of the 7-year period, the patient sustained a cerebral infarction due to atherosclerosis of the right vertebral artery; the angiogram revealed both atherosclerosis and the tumor compressing the right vertebral artery. After the stroke\/ischemic event, the tumor progressively shrunk on MR images obtained for the following 4 years, and the spinal cord compression was similarly relieved.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Here, we report on a 57-year-old man with cervical MR images revealing that a cervical dumbbell schwannoma was progressively compressing both the spinal cord and the right vertebral artery. However, following a cerebral infarction, the tumor underwent spontaneous shrinkage over the next 4 years, thus relieving the compression.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_613_2023","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T05:38:23Z","timestamp":1693546703000},"page":"301","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cervical dumbbell-type tumor spontaneously shrinking following an ischemic stroke"],"prefix":"10.25259","volume":"14","author":[{"given":"Kota","family":"Nakajima","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Kobe City Medical Center General Hospital, Kobe, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshinori","family":"Maki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hikone Chuo Hospital, Hikone, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshinari","family":"Kawasaki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Japanese Red Cross Otsu Hospital, Otsu, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Motohiro","family":"Takayama","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Japanese Red Cross Otsu Hospital, Otsu, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2023,8,25]]},"reference":[{"key":"10.25259\/SNI_613_2023\/ref-1","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1016\/0090-3019(85)90184-3","article-title":"Subarachnoid hemorrhage due to a spinal neurinoma","volume":"24","author":"De Divitiis","year":"1985","journal-title":"Surg Neurol"},{"key":"10.25259\/SNI_613_2023\/ref-2","doi-asserted-by":"crossref","first-page":"1015","DOI":"10.3171\/jns.1978.48.6.1015","article-title":"Subarachnoid hemorrhage and papilledema due to a cervical neurilemmoma.
