Filum Terminale Ependymoma Mimicking Lumbar Disc HerniationAhmet MENKÜ, R. Kemal KOÇ, Bülent TUCER, Onur KULAKSIZOĞLU, Hidayet AKDEMİRDepartment of Neurosurgery, School of Medicine, Erciyes University, Kayseri,TurkeyKey Words: Ependymoma, filum terminale, lumbar disc herniation, magnetic resonance imaging, spinal massThis study presents a case of filum terminale ependymoma with an initial diagnosis of lumbar disc herniation. Compression of nerve fibers by an intradural mass due to filum terminale ependymoma is extremely rare and should be considered in the differential diagnosis of lumbar disc herniation. It is very important to recognize it in the postoperative period because of the changes that occur during the recovery period. Differences between epidural scar, recurrent disc herniation or spinal mass can usually be determined by magnetic resonance imaging. In this study, we also emphasized the importance of contrast-enhanced magnetic resonance imaging.
