Laboratory examination revealed an increased protein content in the cerebrospinal fluid and a normal myelogram. Autopsy disclosed epidermoid carcinoma in the left lower lobe of the lung, intramedullary metastasis at the midthoracic level, and a central pencil-shaped softening above and below the metastatic lesion. The pencil-shaped softening was an ischemic infarct rather than of hemorrhagic or congestive origin. The pathogenesis of this rare association may be explained by the hypothesis of a tumor embolus in the arterial circulation that feeds the center of the cord, producing metastasis. This embolus was followed later by a second embolus to a radicular artery, causing the pencil-shaped softening of the spinal cord.<\/jats:p>","DOI":"10.3171\/jns.1980.52.5.0718","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:43:40Z","timestamp":1241711020000},"page":"718-721","source":"Crossref","is-referenced-by-count":27,"title":["Intramedullary spinal cord metastasis associated with pencil-shaped softening of the spinal cord"],"prefix":"10.3171","volume":"52","author":[{"given":"Genjiro","family":"Hirose","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kohei","family":"Shimazaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matsuhei","family":"Takado","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Kosoegawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuo","family":"Ohya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akio","family":"Mukawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Brain","doi-asserted-by":"publisher","first-page":"159","DOI":"10.1093\/brain\/89.1.159","article-title":"Progressive myelopathy as a sequel to traumatic paraplegia.","volume":"89","author":"Barnett","year":"1966"},{"key":"b2","series-title":"Ann Intern Med","doi-asserted-by":"publisher","first-page":"38","DOI":"10.7326\/0003-4819-16-1-38","article-title":"The role of the vertebral veins in metastatic processes.","volume":"16","author":"Batson","year":"1942"},{"key":"b3","series-title":"Rev Clin Esp","first-page":"56","article-title":"Metastasis tumorales intramedulares.","volume":"108","author":"Boixados","year":"1968"},{"key":"b4","series-title":"Schweiz Arch Neurol Neurochir Psychiatr","first-page":"257","article-title":"Metastasen der Wirbels\u00e4ule und des R\u00fcckenmarks.","volume":"102","author":"Chade","year":"1968"},{"key":"b5","series-title":"Neurol Med Chir","doi-asserted-by":"publisher","first-page":"25","DOI":"10.2176\/nmc.10.25","article-title":"A long follow-up study of 128 cases of intramedullary spinal cord tumours.","volume":"10","author":"Chigasaki","year":"1968"},{"key":"b6","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"1222","DOI":"10.1212\/WNL.22.12.1222","article-title":"Intramedullary spinal cord metastases.
