This monograph begins with a description of the normal anatomy of the suprasellar region; the clinical symptoms and roentgen findings in cases of suprasellar meningioma, based on 22 cases observed in the neurosurgical service of Clovis Vincent in the Hôpital de la Pitié, are then fully described. Certain clinical groups are identified, and their diagnosis and treatment are carefully considered. Suprasellar meningiomas arise from the tuberculum sellae and from the jugum sphenoidale. Those arising from the tuberculum sellae are small and must be carefully dissected between the clinoid processes and the optic nerves ; those arising from the jugum sphenoidale are larger and may grow to occupy the interhemispheric space, raising and separating the frontal lobes. The former raise the chiasm and cause bitemporal hemianopia. The tumors which arise more anteriorly have time to reach a certain size before making any contact with the optic nerves, and the unilateral
