Excerpt from New York Medical Journal, Vol. 83: Incorporating the Philadelphia Medical Journal and the Medical News; April 7, 1906 As will be seen from the description and the illustrations the tumor originated from the dura mater just in advance of the sella turcica, and at the posterior inner angle ofthe orbital plate of the right frontal bone. As it grew upward it penetrated the brain and formed a large cavity in the base, mainly in the orbital surface of the right frontal lobe. In its invasion of the brain it destroyed both olfactory tracts, nearly destroyed the optic nerves and chiasma and thrust the cerebral structures before it, becom ing almost wholly imbedded within the brain sub stance, yet the growth had no organic connection with the brain except slight incorporation with the leptomeninges. The case furthermore confirms the claim of the writer that when tumors of this kind are accessible, do not involve vital portions of the brain, and are mot'oi too large size, they are the most favorable of all intracranial tumors for surgical treatment. When small, they may be easily enucleated without serious damage to the brain and without any fear of recurrence. Even in the present case there were theoretically no insurmountable obstacles to removal except the large size of the growth, the situation, and the mechanical difficulties attending its detach ment from the seat of origin. These tumors grow slowly, and are sharply circumscribed so that in some cases when interfering with well recognized cerebral functions it may be possible to accurately localize them: and in such cases if accessible their early removal is of the highest importance.
