Ependymomas account for 3 to 9% of all neuroepithelial tumors and, although occurring most often within the ventricular system, they may arise from the extraventricular parenchyma as well. Several histologic patterns of these neoplasm are well known, but little attention has been devoted to a variant composed of giant elements. We describe the case of a(More)

Benign fibrous histiocytomas (BFHs) are tumors with fibroblastic and histiocytic components without histological anaplasia. Intracerebral lesions are exceptional and to our knowledge a spinal location was not yet described. We describe 2 cases of BFHs of the neural axis: the first, a 22-month-old boy with Down's syndrome, presented with a paraparesis and(More)
OBJECTIVE Papillary glioneuronal tumors (PGNT) is well-recognized in the literature, although reports usually have not attempted a critical analysis of their characteristics. We report two PGNT and perform a comprehensive review of the published cases, aiming to clarify their clinical, imaging and histopathological features. MATERIAL AND METHODS We have(More)
Gangliogliomas are glioneuronal tumours of the young, and occur more frequently supratentorially. Among those uncommon cases in the spinal cord, the conus medullaris is an extremely rare site. We reviewed the literature of such cases and report another case of a ganglioglioma of the conus in a 13-year-old boy with an insidious sensory sensitive and motor(More)
Four different approach routes have been used to perform the selective amygdalohippocampectomy for the surgical treatment of epilepsy: transcortical through the middle T2 gyrus [1], translyvian through the deep sylvian fissure, transcortical subpial through the anterior T1 gyrus [2] and transcortical through the first temporal sulcus [3]. The choice between(More)
