Sacral myxopapillary ependymoma with extensive osteolysis.

Abstract  Myxopapillary ependymoma rarely presents as a primary intra-sacral lesion and extensive bony destruction is unusual. Radiological features do not help in distinction from other commoner sacral tumors, like chordoma. Hence, histopathology serves as the best diagnostic modality for this differentiation. We report the case of a 42-year-old man with a primary intra-sacral myxopapillary ependymoma causing extensive osteolysis. [ABSTRACT FROM AUTHOR]
