Multifocal intradural extramedullary ependymoma. Case report.
In this paper, the authors present the case of a patient with multifocal intradural extramedullary ependymoma, and they review 18 previously reported cases. A 32-year-old man presented to the authors' institution with a 1-month history of partial medullary syndrome. Magnetic resonance imaging of the neuraxis revealed multifocal intradural extramedullary lesions at the bulbomedullary junction and C2-3, T5-11, L-2, L-4, L-5, and sacrum. ⋯ Intradural extramedullary ependymomas are rare, they predominate in women in the 5th decade of life, and pain is the most frequent initial symptom. The extent of resection and the presence of meningeal infiltration seem to be key determinants of prognosis. The present case is the first intradural extramedullary ependymoma (with the exception of those occurring at the conus medullaris and terminal filum) with multiple lesions at presentation.
