Abbreviations
- Nasal glioma (NG)
- Extranasal glioma (ENG), intranasal glioma (ING)
- Nasal glioma (NG)
Synonyms
- Nasal cerebral heterotopia, glial heterotopia
Definitions
- Developmental mass of dysplastic neurogenic tissue sequestered & isolated from subarachnoid space
- Glioma is misnomer as this is nonneoplastic tissue
- Best thought of as cephalocele without intracranial connection to brain
