Imaging in a new pediatric brain tumor-a supratentorial neuroepithelial tumor with PLAGL1 fusion.

Molecular diagnostics have dramatically influenced the classification of tumor groups in the 2021 WHO CNS tumor classification. Studies focusing on molecular diagnostics continue to identify new tumors. Soon after the summary of the new classification was published, "Supratentorial Neuroepithelial Tumor with PLAGL1 Fusion" was described as a distinct entity. Although this new entity is defined pathologically, its imaging features are undefined. This case report discusses the imaging findings and possible differential diagnosis of the new tumor.
