Differential diagnosis of a solid cystic lesion in supratentorial location includes glioma,1 meningioma,2 metastatic tumor,3 or hemangioblastoma.1 Cystic meningioma is relatively a rare tumor.2 Among various histological variants of meningioma, the meningothelial type most frequently demonstrates cystic changes.3 Richly vascularized meningiomas of the angiomatous type were reported only in a fe...

BACKGROUND Intraparenchymal schwannomas in the central nervous system are very rare. Because most of these are benign, complete excision is the treatment of choice. Further, their radiological findings are difficult to differentiate from glioma. Because Schwann cells are not indigenous to cerebral parenchyma, a lot of speculation has been attached to their origin. CASE DESCRIPTION We report o...

Eighty patients with intrinsic tumors of the cerebral hemispheres and thalami were studied with a 0.5 T superconducting system and third- or fourth-generation computed tomographic (CT) scanners. Twenty-eight patients had histologically verified gliomas, 34 were presumed to have primary brain tumors on clinical grounds, 13 had metastases, and five were postoperative. Lesions shown on CT were equ...

AIM To study the outcome and recurrence in supratentorial anaplastic ependymoma. METHODS Sixteen cases of supratentorial anaplastic ependymoma were reviewed. The average age of presentation was 8.2 years ranging from 1 to 16 years of age. The mean duration between the onset of first symptoms to time of presentation was 4.2 months. Follow-up ranged from 5 to 58 months with a mean of 16.8 month...

OBJECTIVE To estimate longitudinal changes in a quantitative whole-brain and tract-specific MRI study of multiple sclerosis (MS), with the intent of assessing the feasibility of this approach in clinical trials. METHODS A total of 78 individuals with MS underwent a median of 3 scans over 2 years. Diffusion tensor imaging indices, magnetization transfer ratio, and T2 relaxation time were analy...

Cerebellar glioblastomas (GBMs) are rare, with neither their pathogenesis nor prognosis being completely understood. The present study aimed to clarify the clinical characteristics of cerebellar GBMs by comparison with supratentorial GBMs, focusing particularly on the pathogenesis. The clinical factors between cerebellar (n=10) and supratentorial (n=216) GBMs were compared. Additionally, p53 an...

BACKGROUND AND PURPOSE Infratentorial abnormalities may cause cognitive deficits, but current research criteria for vascular dementia (VaD) do not consider them. Our purposes were to determine the prevalence of infratentorial abnormalities in VaD, their relation with supratentorial abnormalities, and whether they are relevant to cognition. METHODS We examined 182 patients (120 men, mean age=7...
