In a previous study1 was described a definite clinical picture noted in patients with a meningeal fibroblastoma arising from the lesser wing of the sphenoid bone. That investigation was based on four cases, and all the characteristics of this tumor were not included. Since that communication was published five other patients with a tumor in the same location and manifesting additional signs and symptoms have come under observation. These five cases are reported here in detail, and all nine are discussed in order to clarify the syndrome.
The signs presented by such a tumor are caused by involvement of the structures in the region of the lesser wing of the sphenoid bone (fig. 1). The most significant of these structures are the optic nerve and chiasm, which lie medially and slightly posterior to the lesser wing. The third, or oculomotor, nerve pierces the dura just lateral to the
