Abstract Glioblastoma multiforme (GBS) is a highly malignant glioma that rarely presents as an infratentorial tumor. Multicentric gliomas lesions are widely separated in site and/or time and its incidence has been reported between 0.15 and 10%. Multicentric gliomas involving supratentorial and infratentorial region are even more rare. In most cases, infratentorial disease is seen after surgical...

OBJECTIVE To compare the age distribution and characteristic MR imaging findings of ependymoma for each typical location within the neuraxis. MATERIALS AND METHODS During a recent eleven-year period, MR images of 61 patients with histologically proven ependymomas were obtained and retrospectively reviewed in terms of incidence, peak age, location, size, signal intensity, the presence or absen...

Metabolic syndrome (MetS) has been associated with silent brain lesions; however, there are no data on the relationship between MetS and the incidence of cerebral microbleeds (CMBs) in Asian populations. The aim of this study was to evaluate the longitudinal association between MetS and incidence of CMBs in the Japanese population. We performed a prospective cohort study involving 684 Japanese ...

BACKGROUND Glioblastoma multiforme (GBS) is a highly malignant glioma that rarely presents as an infratentorial tumor. Multicentric gliomas lesions are widely separated in site and/or time and its incidence has been reported between 0.15 and 10%. Multicentric gliomas involving supratentorial and infratentorial region are even more rare. In most cases, infratentorial disease is seen after surgic...

The aim of this study was to perform for the first time the intracranial volumetric analysis of cerebrospinal fluid (CSF) and brain parenchyma in the supratentorial and infratentorial space in a 30-year-old female patient with hydranencephaly and macrocephaly. A head scan performed using a 3T magnetic resonance was followed by manual segmentation of the brain parenchyma and CSF on T2 coronal br...

BACKGROUND AND PURPOSE Cerebral microbleeds are associated with aging, hypertension, and Alzheimer disease. Microbleeds in a lobar distribution are believed to reflect underlying amyloid angiopathy, whereas microbleeds in the deep gray matter and infratentorial brain are commonly seen with hypertension. However, it is unknown how microbleeds in either distribution are related to Alzheimer patho...

OBJECTIVE To determine whether cognitive function is associated with white matter hyperintensities (WMH) in patients with infratentorial stroke. METHODS This was a retrospective, cross-sectional study. Twenty-four first-ever infratentorial stroke patients between 18 and 60 years of age were enrolled. WMH was evaluated by the Fazekas scale and the Scheltens scale. Cognitive functions were asse...

BACKGROUND AND PURPOSE We investigated regional differences in MRI characteristics and risk factor profiles of incident lacunes over a 3-year period. METHODS Baseline and 3-year follow-up MRI were collected within the LADIS study (n=358). Incident lacunes were characterized with respect to brain region, their appearance within pre-existent white matter hyperintensities (WMH), surrounding WMH ...
