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. see [[Meningioma en plaque of the sphenoid ridge]]. see [[Sphenoorbital meningioma]] ---- 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 ===== Lateral sphenoid wing meningioma or pterional meningioma ===== [[Lateral sphenoid wing meningioma]] ===== Medial sphenoid wing meningioma classification ===== [[Medial sphenoid wing meningioma classification]].
