| Popis: | Primary intramedullary spinal cord tumors (IMSCTs) are rare entities, accounting for 2–4 % of all the central nervous system tumors. The prevalence of these tumors varies according to gender, histological type, races, and age: in particular, IMSCTs represent 20 % of adult and 35 % of pediatric spine tumors. The most frequent IMSCTs are of glial origin (80–90 %), of which 60–70 % are ependymomas and 30–40 % are astrocytomas. The prevalence of these forms changes with age, since the three ependymal subtypes (ependymoma, subependymoma, and myxopapillary ependymoma) are the most common in adults, while astrocytomas are mostly diagnosed in children. Myxopapillary tumors are not really intramedullary tumors, since they grow from the filum terminale, but they may occasionally migrate into the conus. |
