Özet

Posterior fossa tumors (PFTs) represent approximately 50% of all pediatric brain tumors. Among these, medulloblastoma (MB) and ependymoma (EP) are the most common subtypes, frequently overlapping in both location and imaging characteristics—particularly within the fourth ventricle. Radiomics enables the extraction of quantitative features from MRI and holds promise for enhancing diagnostic differentiation. However, radiomics applications in pediatric PFTs remain limited. This study aims to identify radiomics-based differences between MB and EP and to evaluate the performance of machine learning techniques in their classification.
