  • benign
  • Central neurocytoma, abbreviated CNC, is an extremely rare, ordinarily benign intraventricular brain tumour that typically forms from the neuronal cells of the septum pellucidum. (wikipedia.org)
  • However, as more information was gathered the name benign central neurocytoma was started to be seen as a double misnomer because these tumors are not always benign nor centrally located. (wikipedia.org)
  • Tumor samples stained using H&E stain and examined under the microscope revealed that CNC is a well-differentiated tumor with benign histological features. (wikipedia.org)

  • optic chiasm
  • for instance, if the hypopituitarism is due to a growth hormone-producing tumor, there may be symptoms of acromegaly (enlargement of the hands and feet, coarse facial features), and if the tumor extends to the optic nerve or optic chiasm, there may be visual field defects. (wikipedia.org)
  • nervous system

  • Central neurocytomas are classified as a grade II tumor under the World Health Organization's classification of tumors of the nervous system. (wikipedia.org)
  • Without a doubt, astroblastoma remains one of the most challenging and problematic tumors to diagnose and treat among all nervous system cancers. (wikipedia.org)
  • Calcification deriving from nervous system tumors is a rare quality in astroblastoma patients, but it is nonetheless easy to identify. (wikipedia.org)
  • diagnosis
  • The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause, such as tumors of the pituitary, and the ideal treatment. (wikipedia.org)
  • Outcome varies considerably depending on the type of tumor and how far it has spread at diagnosis. (wikipedia.org)
  • surgery
  • We feel with further studies, LITT will continue to develop into a safer, more user-friendly technique that may help remove more of these deadly tumors than surgery alone can accomplish," said Dr. Sloan. (eurekalert.org)

  • Glioma
  • Tumors of this type usually arise from the cerebrum and may exhibit the classic infiltration across the corpus callosum, producing a butterfly (bilateral) glioma. (wikipedia.org)
