Glioblastoma Multiforme of the Conus Medullaris in a Child: Description of a Case and Literature Review

of the conus medullaris in a child. MR imaging showed at the T12-L1 level an intramedullary mass with signal alter-ation, with only two nodules of contrast enhancement. The finding was consistent with astrocytoma. Pathologic evalu-ation was consistent with glioblastoma multiforme. Nine months after the surgical treatment, the patient showed leptomeningeal recurrence. This case appears to be un-usual for both the hysto-type and the nonspecific MR im-aging features. Spinal neoplasms in the adult population are rep-resented mostly by extradural (55%) and intradural extramedullary tumors (40%), whereas intramedul-lary tumors are rare (5%) (1). In contrast, the rate of intramedullary tumors in children is higher, up to 35 % of all spinal neoplasms (2). According to litera
