Hemangioblastomas are uncommon lesions that represent nearly 4% of the tumors of the spinal cord. Three fourths of them are sporadic, and the remainder are components of von Hippel Lindau (VHL) disease.1,2 They are mostly found in the cerebellum, although they can develop in the brain stem or spinal cord; of the latter, they are only rarely located in the filum terminale.3 The filum terminale i...

The filum terminale plays an important role in the pathophysiology of tethered cord syndrome (TCS). The study on ultrastructure of fetal filum can provide reference standard for diagnosis of TCS. Eleven fresh Chinese human aborted fetuses had their fila measured and removed. Transverse and longitudinal sections of the middle and distal segments of fila were submitted for scanning electron micro...

BACKGROUND Giant cell ependymoma of the filum terminale is a rare variant, generally manifested as a well-circunscribed intradural mass with an indolent biological behavior. CASE PRESENTATION We describe the case of a 48-year-old Mexican female who non-relevant past medical history, that developed a GCE of the filum terminale. Magnetic resonance imaging and computed tomography revealed the pr...

Hemangioblastomas are benign tumours affecting the central nervous system (CNS) as sporadic case or as manifestation of von Hippel Lindau disease (VHL), a neoplastic multistemic autosomal dominant syndrome predisposing to develop CNS and visceral lesions. Hemangioblastomas are predominantly originating in the cerebellum and in the cervical and thoracic spinal cord; localization at the cauda equ...

ependymomas accounts for about 2%–6% of cns and 60%–70% of spinal cord tumors. several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. in spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. this report presents a case of giant cell ependymoma...

BACKGROUND AND PURPOSE Spinal arteriovenous shunts below the conus constitute 3 types of lesions, which have previously been mainly described in case reports, given their rarity, and are sometimes misdiagnosed. The purpose of this study was to describe the features of each type and compare these types as to epidemiologic features, clinical and radiologic presentations, treatment, and outcomes i...
