Area of Science:

  • Pediatric neuro-oncology
  • Neuroradiology
  • Molecular pathology

Background:

  • Cortically based brain tumors in children are diverse and challenging to diagnose.
  • Radiologists are key members of the multidisciplinary team managing these cases.
  • Accurate and timely diagnosis is crucial for effective treatment planning.

Purpose of the Study:

  • To develop a clinically useful, easy-to-follow flowchart for the differential diagnosis of pediatric cortical brain tumors.
  • To integrate current imaging characteristics, epidemiologic data, and molecular understanding into the diagnostic algorithm.
  • To align the diagnostic approach with the 2021 World Health Organization (WHO) classification of CNS tumors.

Main Methods:

  • Development of an algorithm tree based on typical imaging features.
  • Inclusion of relevant epidemiologic data for differential diagnosis.
  • Consideration of the 2021 WHO classification and recent molecular insights.
  • Highlighting classic and newly identified pathologic subtypes.

Main Results:

  • A structured diagnostic algorithm for pediatric cortical brain tumors has been created.
  • The algorithm incorporates imaging, epidemiology, and molecular data.
  • It addresses both common and rare tumor subtypes according to the latest WHO guidelines.

Conclusions:

  • The proposed flowchart provides a systematic approach to diagnosing pediatric cortical brain tumors.
  • It aids radiologists in differentiating complex tumor entities.
  • This tool supports precise diagnosis by integrating updated classifications and molecular information.
