In these locations, schwannomas can resemble other more common intra-axial cystic neoplasms including pilocytic astrocytoma, pleomorphic xanthoastrocytoma [7], meningioma if near a centrally located nerve root [9, 10, 13, 14], or less commonly a high-grade glial tumor [11].

It is a rare glial tumor that usually appears submucosally as a pedunculated mass in the midline, attached to the nasal septum.

Nasal glioma (neuroglial heterotopia) mimicking an astrocytoma: case report

GP is often mixed with GTS series despite this being a separate entity [13] because it is defined by pure mature glial tumor tissue in the peritoneum [29-31] and is encountered in a variety of clinical scenarios [29, 32, 33].

The discovery of an IDH mutation or H3 mutation in a glial tumor argues strongly against the diagnosis of a poorly infiltrative glioma.

Genomic Analysis in the Practice of Surgical Neuropathology: The Emory Experience

The lesion, despite some similarities (clusters of voluminous neurons with thick bundles of nerve cell processes) is completely different from a tumoral ganglioneuroma or a cerebellar ganglioglioma in which variable architecture discloses proliferation of both abnormal neurons and glial tumor cells.

Although they are the most common intramedullary glial tumor in adults, ependymomas are the second most common spinal cord neoplasms in children.

Focal spinal cord lesions in children: a practical approach to differential diagnosis

Synaptophysin or neuron-specific enolase positivity on immunohistochemistry, or the presence of typical or abortive synapses, neurosecretory granules or neuritic processes on ultrastructural examination, demonstrate the neuronal lineage of the tumor cells, not found in glial tumor and support the diagnosis of CN (p.
