Abstract

A 65-year-old woman presented with a history of severe lower back pain on forward-flexion for 2 months duration. Magnetic resonance Imaging revealed a high signal mass with a tail on T1-weighted images at the L3 level. A total surgical resection was performed via a posterior approach with the aid of a microscope. Histopathological examination of the tumor revealed two pathological components : lipoma and myxopapillary ependymoma. The presence of dual histological components in one spinal cord tumor is rare. There are no prior reports of both types of cells [adipose and ependymal] grown simultaneously in a single tumor of the filum terminale in the medical literature. We report a unique case of the co-existence of lipoma and myxopapillary ependymoma within the same tumor located at the filum terminale and review related literature.
