Pediatric brain tumors, such as medulloblastomas and low-grade astrocytomas, differ from adult brain tumors in histology and location. This review outlines key imaging criteria for common childhood brain tumors.

Area of Science:

  • Pediatric Oncology
  • Neuroradiology
  • Neuro-oncology

Background:

  • Brain tumors exhibit distinct histological and localization patterns in pediatric versus adult populations.
  • Malignant gliomas and meningiomas are common in adults, whereas medulloblastomas and low-grade astrocytomas are prevalent in children.
  • Pediatric brain tumors predominantly occur in the infratentorial region (50-70%), contrasting with the approximately 30% infratentorial incidence in adults.

Purpose of the Study:

  • To differentiate common pediatric brain tumors from adult types.
  • To highlight the characteristic locations and imaging features of pediatric brain tumors.
  • To provide essential imaging criteria for diagnosing common pediatric brain tumors.

Main Methods:

  • Review of diagnostic imaging modalities including sonography, cranial computed tomography (CCT), and magnetic resonance imaging (MRI).

  • Analysis of space-occupying characteristics, density, and intensity variations compared to normal brain parenchyma.
  • Description of extrusive growth, parenchymal infiltration, and intrinsic origins of tumors.

    • Main Results:

    • Identification of key differences in tumor types (e.g., medulloblastoma, astrocytoma) and their locations between pediatric and adult populations.
    • Recognition of brain tumors via imaging based on mass effect and signal/density alterations.
    • Outline of the most common pediatric brain tumors: astrocytoma, medulloblastoma, brainstem glioma, craniopharyngioma, neurofibromatosis, and ganglioglioma.

    Conclusions:

    • Understanding the unique characteristics of pediatric brain tumors is crucial for accurate diagnosis.
    • Imaging plays a vital role in identifying and characterizing brain tumors in children.
    • This article provides a foundational overview of common pediatric brain tumors and their imaging criteria.
