OBJECTIVE Neurenteric cysts (NCs) typically arise as benign ventral intradural extramedullary developmental malformations of the spine which contain heterotopic epithelium resembling the intestinal or respiratory tracts. Intracerebral NCs are extremely rare, though the frequency of symptomatic reports and incidental findings is increasing, perhaps because(More)
BACKGROUND Magnetic resonance-diffusion tensor imaging (DTI) was used to predict motor outcome for patients with intracerebral hemorrhage. We compared the predictive accuracy of data sampled from the cerebral peduncle with data from the corona radiata/internal capsule. This study included 32 subjects with thalamic or putaminal hemorrhage or both. METHODS(More)
Several neurosurgical studies have provided descriptions of the utility of fluorescence-guided tumor resection using a microscope. However, fluorescence-guided endoscopic detection of a deep-seated brain tumor has not yet been reported. The authors report their experience with an endoscopic biopsy procedure for a malignant glioma within the third ventricle(More)
A 68-year-old woman presented with a rare huge right occipital cystic lesion manifesting as progressive left hemiplegia. Cranial computed tomography revealed a 4 x 7 cm right occipital lobe thin-walled cyst with midline shift and compression of the ipsilateral ventricle. The patient underwent a single burr hole operation for cystography and delineation of(More)
INTRODUCTION Arteriovenous malformations (AVM) are considered to be static congenital lesions; however, a subset may possess dynamic pathophysiological capabilities of growth, regression or other morphological changes with time. We report on an adult patient harboring a pineal AVM who presented with progressive symptoms of obstructive hydrocephalus and was(More)
A 30-year-old man presented with a generalized seizure manifesting as decreased consciousness. Diffusion-weighted magnetic resonance imaging showed transient areas of high intensity in the gray and subcortical white matter of the left occipital and temporal lobes. The lesions did not reflect the vascular territories. After a period of over 2 weeks, his(More)
This study examined the clinical usefulness of magnetic resonance-diffusion tensor imaging (DTI) for predicting motor outcome in patients with intracerebral hemorrhage. We studied 15 subjects (age range, 31-81 years) diagnosed by conventional computed tomography with thalamic hemorrhage, putaminal hemorrhage, or both. DTI data were obtained on days 14-18(More)
Colloid cysts of the third ventricle presenting with acute obstructive hydrocephalus due to intracystic and intraventricular hemorrhage are extremely rare. The authors report a case of a 43-year-old man with a hemorrhagic colloid cyst that was treated using endoscopic surgery. A small colloid cyst of the third ventricle was initially diagnosed in the(More)
We describe a rare case of an arteriovenous malformation (AVM) embedded in the vestibulocochlear nerve presenting with subarachnoid hemorrhage (SAH) treated by microsurgical elimination of the main feeding artery and partial nidus volume reduction with no permanent deficits. This 70-year-old woman was incidentally diagnosed 4 years previously with two small(More)
