Anaplastic ependymoma of spinal cord presented with low back pain A 53-year-old man was admitted to our Neurosurgery Department with low back pain since 1 week. Neurologic examination was normal. Magnetic resonance imaging was performed. Magnetic resonance imaging showed an intradural extramedullary mass at the filum terminale (Figure). The patient was referred to neurosurgery clinic for surgical treatment. Pathologic findings were was found to be a World Health Organization Grade III anaplastic ependymoma. Spinal ependymoma occupies 40% to 60% of primary spinal cord tumors and they account for 60% of all intramedullary tumors. However, intradural extramedullary tumors are extremely rare. The tumor most commonly arises from the central canal of the spinal cord, the conus medullaris, or the filum terminale. Intraoperative findings of these tumors have shown wellcircumscribed encapsulated tumors with no dural attachment. Tumor can be easily removed from the surface of

the spinal cord. Magnetic resonance imaging is crucial for diagnosis.
