Abstract
In this section, the topics are examined under three subheadings. In the first topic, imaging of pediatric brain tumors, the World Health Organization's 2021 classification of Central Nervous System tumors (CNS WHO5) was taken into account. According to this classification, pediatric brain tumors are subdivided into embryonal tumors, pediatric type diffuse high-grade gliomas, pediatric type diffuse low-grade gliomas, pilocytic astrocytomas, ependymal tumors, glioneuronal or neuronal tumors, choroid plexus tumors, sellar suprasellar tumors and pineal region tumors. separated. The radiological findings of the tumors in question were examined together with the case samples. The second topic, pediatric spinal masses, was classified according to their anatomical location (Intramedullary, Intradural, extramedullary, Extradural) and discussed with their radiological findings. In the third topic, the radiological findings of pediatric head and neck masses are discussed together with their radiological findings according to their anatomical locations such as neck, paranasal sinus, temporal bone and orbit.
