The Many Faces of Myxopapillary Ependymomas.

ABSTRACT: Myxopapillary ependymomas (MPEs), classified as grade 2 tumors by the World Health Organization, are rare spinal neoplasms. Despite their slow growth and generally benign nature, MPEs have a high recurrence rate and potential for CSF dissemination. This study aims to identify the MRI characteristics and pathologic patterns of MPE and investigate potential correlations between the MRI characteristics and specific histopathologic patterns. We assessed 13 patients (7 men; mean age, 45.1 years) with pathologically proved MPE. MR images were reviewed for tumor location, size, T1 and T2 signal characteristics, contrast enhancement, hemosiderin cap presence, vertebral scalloping, drop metastasis, and prominent intradural flow voids. Four histopathologic patterns (microcystic, solid, hemorrhagic,
