• Assessment of ADC values of enhancing solid tumor is a simple and reliable technique for preoperative differentiation of cerebellar tumors in pediatric patients. (ajnr.org)
  • The goal of our retrospective study was to establish the ADC values of different pediatric cerebellar tumors with the hypothesis that these ADC values and ratios allow for differentiation of specific tumor types. (ajnr.org)
  • Children with cerebellar pilocytic astrocytoma may experience side effects related to the tumor itself depending on the location and related to the treatment. (wikipedia.org)
  • The organization's most recent grade in 2007 assigned astroblastoma as a high-grade III and grade IV neoplasm, signifying that the glial tumor is dangerous for patients, causing fatal problems even after surgery. (wikipedia.org)
  • In general, when brain lesions are smaller than Grade I, demarcating between these features is near impossible, often mistaking astroblastoma with glial neoplasms, high-grade astrocytes, and embryonal neoplasms. (wikipedia.org)
  • Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid. (wikipedia.org)
  • The majority of tumors exhibit a spherical perimeter with either a solid or cystic interior, comprising peripheral vasculature and epithelioid neoplasms. (wikipedia.org)
  • 5 - 16 Significant differences in cellularity of pediatric cerebellar neoplasms, particularly between JPAs and medulloblastomas, indicate that these lesions could potentially be distinguished by their ADC values. (ajnr.org)
  • Depending on the location of cerebellar damage, these tremors can be either unilateral or bilateral. (wikipedia.org)
  • Neurodegenerative cerebellar ataxias represent a group of disabling disorders for which we currently lack effective therapies. (bioportfolio.com)
  • Brain MR imaging studies that included ADC maps were retrospectively reviewed in 32 patients with histologically proved cerebellar neoplasm. (ajnr.org)
  • The vermis is intimately associated with all regions of the cerebellar cortex, which can be divided into three functional parts, each having distinct connections with the brain and spinal cord. (wikipedia.org)
  • It sends fibers to deep cerebellar nuclei that, in turn, project to both the cerebral cortex and the brain stem, thus providing modulation of descending motor systems. (wikipedia.org)
  • Bioinformatic analysis of Mtss1 suggests that differential exon usage may affect interaction with Fyn and Src, two tyrosine kinases previously recognized as critical for cerebellar cell migration and histogenesis. (nih.gov)
  • Retrospective review of patient records with histologically proved neoplasm in an electronic data base and PACS was performed in 2 institutions. (ajnr.org)
