abstract
- The purpose of this paper was to introduce and review the characteristic imaging features of ependymal neoplasms through a comprehensive case-based approach. Illustrated cases highlight both common and uncommon manifestations of central nervous system-ependymomas. The combination of imaging features, location of the tumor, and patient's demographics often allow the suggestion of ependymoma as a lead entity in the differential diagnosis. However, significant overlap exists between the radiologic characteristics of ependymomas and those of other tumors commonly encountered in the same locations, which can pose a challenge for a definitive diagnosis based on imaging alone.
