Only 12 cases have been reported in the literature, all since 1965. These lesions occurred in adults, primarily in males, and were located in the cauda equina. Of the 12 lesions, eight were cavernous hemangiomas. The authors report here the clinicopathological features of 10 cases of hemangioma of the spinal nerve root, nine of which were of the capillary type.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Methods.<\/jats:italic> The group included six men and four women who ranged in age from 40 to 62 years. The majority of patients presented with pain and weakness. One patient also experienced worsening of pain during menses. In all cases, gadolinium-enhanced magnetic resonance imaging or computerized tomography myelography demonstrated a discrete intraspinal extramedullary mass. Administration of contrast agent resulted in uniform, intense enhancement. A gross-total resection was achieved in all but one case; in most cases, it was necessary to sacrifice the parent nerve root. Preoperative symptoms and signs improved in nine cases. On histological examination, all but one tumor, a spindle-cell hemangioendothelioma, were shown to be ordinary capillary hemangiomas. Two lesions exhibited a cavernous component, and five showed a partly solid growth pattern resembling juvenile capillary hemangioma. In all cases, the relationship with the nerve root was histologically confirmed. The tumor\u2014nerve relation varied. The intact nerve was displaced by the epineurial mass in three cases. The fascicles appeared separated in six cases, and individual nerve fibers were seen throughout one lesion with endoneurial involvement.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic> Hemangiomas of spinal nerve roots pose a challenging diagnostic problem. Knowledge of their existence is relevant in that they may mimic tumors and are amenable to surgical treatment.<\/jats:p>","DOI":"10.3171\/spi.1999.91.2.0175","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:45:16Z","timestamp":1241711116000},"page":"175-180","source":"Crossref","is-referenced-by-count":14,"title":["Hemangioma of spinal nerve root"],"prefix":"10.3171","volume":"91","author":[{"given":"Federico","family":"Roncaroli","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd W.","family":"Scheithauer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William E.","family":"Krauss","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurochirurgie","first-page":"121","article-title":"[A free meningioma of the cauda equina].","volume":"44","author":"Bouillot","year":"1998"},{"key":"b2","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"226","DOI":"10.1016\/0090-3019(94)90127-9","article-title":"Subarachnoid hemorrhage from cavernous angioma of the cauda equina: case report.","volume":"41","author":"Bruni","year":"1994"},{"key":"b3","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"381","DOI":"10.1016\/0090-3019(94)90031-0","article-title":"Spinal intramedullary cavernous angiomas: a literature meta-analysis.","volume":"41","author":"Canavero","year":"1994"},{"key":"b4","series-title":"Neurosurg Rev","doi-asserted-by":"publisher","first-page":"281","DOI":"10.1007\/BF00383882","article-title":"Cavernous angioma of the cauda equina: report of two cases and review of the literature.","volume":"18","author":"Cervoni","year":"1995"},{"key":"b5","series-title":"Acta Neuropathol","doi-asserted-by":"publisher","first-page":"173","DOI":"10.1007\/BF00687739","article-title":"Glial fibrillary acidic protein in stromal cells of some capillary hemangioblastomas: significance and possible implications of an immunoperoxidase study.","volume":"54","author":"Deck","year":"1981"},{"key":"b6","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"442","DOI":"10.1016\/S0090-3019(97)00354-6","article-title":"Cavernous angiomas of the cauda equina: case report and review of the literature.","volume":"50","author":"Duke","year":"1998"},{"key":"b7","series-title":"Soft Tissue Tumors","first-page":"579","article-title":"Benign tumors and tumorlike lesions of blood vessels","author":"Enzinger","year":"1995"},{"key":"b8","series-title":"Conn Med","first-page":"209","article-title":"Intrinsic hemangiomas of the peripheral nerves.
