Abstract:
:Intracranial and intraspinal ependymomas are uncommon tumors of the central nervous system. These tumors have a variety of imaging characteristics, some of which are fairly specific for ependymoma. We discuss the MRI features of ependymomas for each of the typical locations within the neuraxis, and provide MR imaging examples.

杂志文章abstract::The epidemiology of pediatric brain tumor was studied in a 10-year period from 1986 to 1995 in Yamaguchi prefecture. The total number of pediatric brain tumors was 83, and the incidence was 2.5/100, 000/year, which did not change during the period. The sign most frequently seen was intracranial hypertension, whereas f...
