Postlesional plasticity has been identified in patients with cerebral gliomas by inducing a large functional reshaping of brain networks. Although numerous non-invasive functional neuroimaging methods have extensively investigated the mechanisms of this functional redistribution in patients with cerebral gliomas, little effort has been made to investigate the structural plasticity of cortical a...
Although cerebellar involvement across a wide range of cognitive and neuropsychiatric phenotypes is increasingly being recognized, previous large-scale studies in schizophrenia (SZ) have primarily focused on supratentorial structures. Hence, the across-sample reproducibility, regional distribution, associations with cerebrocortical morphology and effect sizes of cerebellar relative to cerebral ...
A 29-year-old man presented with comatose after methadone intoxication. Cerebral tomography only showed cortico-subcortical hypodense signal in the right cerebellar hemisphere. Brain MRI showed a rare imaging of FLAIR and DWI hyperintensities in the two cerebellar hemispheres as well as basal ganglia (globi pallidi), compatible with methadone overdose. To our knowledge this is the first reporte...
BACKGROUND Brain magnetic resonance imaging (MRI) findings during acute cerebellar ataxia in cases of postinfectious cerebellitis are frequently normal. This has resulted in the use of other imaging modalities, such as single-photon emission computed tomography, to aid diagnosis. OBJECTIVE To illustrate the chronologic occurrence of cerebellar ataxia, abnormal findings on MRI, and cerebral sp...
During the procedure of carbon monoxide (CO) poisoning, the craniocerebral injury mainly locates in the bilateral cerebral subcortical white matter, globus pallidus, or internal capsule; therefore, CO poisoning-resulted isolated large-area cerebellar damage and secondary extensive cerebellar atrophy is extremely rare. This study reported the clinical symptoms, signs, imaging features, diagnosis...
Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms. On the other hand, a persistent trigeminal artery variant feeding both the anterior inferior cerebellar artery and the posterior inferior cerebellar artery territory is ve...
BACKGROUND A few studies have been conducted on the relationship between cerebellar volume and emotional memory or clinical severity in major depressive disorder (MDD). In this study, we aimed to compare the volume and density of the cerebellar gray matter (GM) in patients with MDD and in healthy controls (HCs) and explore the association between these cerebellar parameters and measurements of ...
The neurologic manifestations of trichinosis are diverse, and range from encephalopathy to cerebral, cerebellar, and spinal cord abnormalities.
Drug abuse has been claimed to cause the loss of neurons and reduction of volume in both the adult and developing brain. This study examined cortex volumes in cerebrum and cerebellum of male rats that were dependent on morphine using unbiased stereological counting methods and systematic random sampling technique. Our goal was to test whether short time exposure to morphine can affect the corte...
Background: Neurofibromatosis type 1 (NF1) is a genetic disorder with diverse phenotypic manifestations. Cerebral vasculopathy one of the multisystem involvements often overlooked unless symptomatic. Case Report: A 28-year-old male patient prolonged NF1 complained right-hand position-specific rhythmic tremor after surviving an ipsilateral cerebellar arteriovenous malformation (AVM) hemorrhagic ...
