- Astrocytoma
- Desmoplastic infantile ganglioglioma (DIG)
- Dysembryoplastic neuroepithelial tumor (DNET)
- Ependymoma
- Focal cortical dysplasia
- Ganglioglioma
- Glioblastoma
- Oliogodendroglioma
- Pleomorphic xanthoastrocytoma (PXA)
- Primitive neuroectodermal tumor (PNET)
Approach to the differential diagnosis of supratentorial brain tumors:
- Most are glial tumors – astrocytoma (most common), oliogodendroglioma, glioblastoma
- Peripherally located tumors that involve cortex, are low grade, may cause seizures – ganglioglioma, dysembryoplastic neuroepithelial tumor, pleomorphic xanthoastrocytoma, oliogodendroglioma
- Peripherally located tumors that involve cortex, are high grade – desmoplastic infantile ganglioglioma
- Primitive neuroectodermal tumor and ependymoma are less common
- Focal cortical dysplasia is often difficult to definitively differentiate from a brain tumor on imaging
