In [[1938]], [[Harvey Williams Cushing]] and [[Louise Eisenhardt]] reported the first surgical experience with [[sphenoid ridge meningioma]]s. On the basis of clinical observations and anatomic characteristics obtained during [[surgery]] or [[autopsy]] in 53 patients, they divided sphenoid ridge meningiomas into four categories: 

1) Tumors of the deep or clinoidal third

2) Middle-ridge tumors

3) En plaque pterional tumors

4) Global pterional tumors
((Cushing H, Eisenhardt L: Meningiomas: Their Classification, Regional Behavior,
Life History, and Surgical End Results. Springfield, Charles C. Thomas, 1938.))

Categorizing globoid tumors into 3 groups: 

1) [[Medial sphenoid wing meningioma]] or [[clinoidal meningioma]].

2) Middle

3) [[Lateral sphenoid wing meningioma]] or [[pterional meningioma]]

Tumors found in the external third of the sphenoid are of two types: en-plaque and [[globoid meningioma]]s. 

Patients with globoid meningiomas often present only with signs of increased intracranial pressure. This leads to various other symptoms including headache and a swollen optic disc.

----
On the basis of a 20-year experience with 60 surgically treated patients with sphenoid wing meningiomas, we have modified Cushing’s classification system by dividing these
tumors into three groups: Group I, global medial ridge (35
patients); Group II, global lateral ridge (13 patients); and Group
