This video shows an exoscope-guided single-stage resection with 3-dimensional technology of a supratentorial cavernoma and a supratentorial hemangioblastoma during the same surgical procedure. The patient is a 42-yr-old man with a history of generalized tonico-clonic seizures. Contrast-enhanced
Hemangioblastoma (HB) in the supratentorial region of the brain is rare and only a few cases are reported on intraventricular HB. HB of the lateral ventricles is even rarer. We present a case of a 30-year-old man with generalized tonic clonic seizures. The brain computed tomography showed a 5.5 cm
Congenital supratentorial hemangioblastomas are extremely rare tumors even in pediatric population. A 57-day-old female neonate presented with a pure motor seizure. On imaging studies, intracranial hemorrhagic lesions containing multiple cystic components in the cerebral and cerebellar areas were
A rare case of hemangioblastoma located in the region of hippocampus is reported. A 27-year-old female presented with a single episode of generalized convulsion. The vascular and cherry red color hemangioblastoma was resected by a temporo-zygomatic approach. There has been no recurrence of tumor at
Thirteen patients (11 males, 2 females) with cerebral hemangioblastomas (HABs) were treated with Gamma Knife radiosurgery (GKR). Four patients had multiple lesions in the brain. The remainder had a single lesion. The total number of lesions was 20. Eight cases had recurrent or residual HABs after
Immunogold electron microscopy was used to analyze and quantify the Glut1 glucose transporter in brain tissue from five patients undergoing surgery for treatment of seizures. Samples were prepared from two different regions of each resection: (1) the most actively spiking epileptogenic site, and (2)
Hemangioblastomas are benign vascular neoplasms that may be associated with von Hippel-Lindau disease. They are more common in men, with a mean age of 36 years, and rarely affect the supratentorial region and, when present in this topography, do not have meningeal impairment. Diagnosis OBJECTIVE
To evaluate the neurological complications after stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT).
METHODS
The Ramathibodi Radiosurgery Unit started its service in August 1997, using the linear-accelerator based system. There were 144 patients treated from August 1997 to
Neurofibromatoses (NF1 and NF2) are genetic diseases with an extremely wide range of manifestations, particularly NF1. In order to gain insight into their prognosis, we have conducted a follow-up study of 100 patients with neurofibromatoses, 89 NF1 patients and 11 NF2 patients all of them presenting
OBJECTIVE
The goal of this study was to evaluate the efficacy and safety of same-day stereotactic aspiration and Gamma knife surgery (GKS) for cystic intracranial tumors.
METHODS
Between 1996 and 2007, 77 patients harboring cystic intracranial tumors underwent a same-day procedure of MRI-guided cyst
We report a case of gangliocytoma at a cortical and subcortical area in the right parietal lobe. The patient had a generalized seizure at 11 years of age. The MRI shows an ill-demarcated high intensity area in T2 weighted images including an enhancing tumor of 10 mm in diameter. At first, the tumor
Pheochromocytomas are frequently associated with inherited cancer syndromes such as von Hippel-Lindau disease (VHL). Retinal angioma and hemangioblastomas of the central nervous system are hallmarks of VHL, but its clinical variety is remarkably broad. Pheochromocytomas as the sole or first
The purpose of this article is to clarify interactions between oral contraception (using low- and high-dose oral contraceptives) and the main neurological diseases occurring in genitally active women. Vascular disorders predominate, since contraception is in itself a well-recognized a risk factor,
A subset of patients experience persistent symptoms after pediatric concussion, and magnetic resonance imaging (MRI) is commonly used to evaluate for pathology. The utility of this practice is unclear. We conducted a retrospective cohort study to describe the MRI findings in children with
OBJECTIVE
Capillary hemangiomas are benign tumors or tumorlike lesions that originate from blood vessels and have rarely been reported to develop in the brain or spinal cord. The authors summarize the clinical and histological features of capillary hemangiomas of the central nervous system
