NEUROGENIC tumors occurring primarily in the nose and the throat are rare, and there are probably few other tumors about which there is so much confusion in the literature. When a neurogenic tumor is encountered, and this is usually unexpectedly, one may be at a loss to know what to do, even though most of them are amenable to successful surgical correction or removal.

Any tumor derived from nerve tissue or its coverings may be considered a neurogenic tumor. Neurogenic tumors of the nose or the throat may be divided into two large groups consisting of, first, developmental errors and, second, neoplasms.

The developmental errors are meningocele, encephalocele and hydroencephalocele. In the literature these have been called sincipital1 or basal hernias,2 encephaloma,3 rhinoencephalocele,4 glioma,5 fibroglioma6 and neurocytoma.7 They are most frequently referred to as meningocele and encephalocele or sincipital or basal hernias.

These three conditions have in common a defect
