Spinal and Leptomeningeal Infantile Glioma With Raf1 Fusion: Diagnostic Challenges for a Potentially Novel Tumour Type

ABSTRACT We report an infantile spinal tumour with diffuse leptomeningeal dissemination and features of a glioma with CUX1::RAF1 fusion and the DNA‐methylation class, infant‐type hemispheric glioma. This strange case was similar to a previously reported tumour reported in the literature, which clustered perfectly with our case. Further reports are needed to confirm the hypothesis that this neoplasm represents a novel tumour type.
