Brain tumors are the second most common malignancy and the most common solid tumors in the pediatric population. Most brain tumors in the pediatric population are primary in origin contrary to the adult population. The various factors useful for establishing the diagnosis include the age of the patient, imaging characteristics, and location of the tumor. Infratentorial tumors are more common between 4 and 10 years of age, whereas supratentorial tumors are common in neonates and infants up to 3 years. Conventional computed tomography and magnetic resonance imaging are of paramount importance in the diagnostic evaluation of these tumors which help in their characterization and allow accurate assessment of their extent. The updated World Health Organization classification of brain tumors has incorporated various genetic and molecular parameters. It is essential for the radiologists to be familiar with the imaging features of genetic tumor subtypes as it plays a role in patient management and prognostication. Advanced neuroimaging provides additional information regarding the metabolism and physiology of these lesions, thereby aiding in their diagnosis and follow-up.
