Axial unenhanced CT images with bone windowing through the skull base
demonstrate a sclerotic and expansile process involving the basis sphenoid
and the right greater and lesser wings, with extension inferiorly to the pterygoid
plates. Also noted is encroachment on the right foramen ovale, pterygopalatine
fossa, the superior orbital fissure, and the sella turcica. There is homogenous
and ground-glass appearance to its matrix.
Coronal CT images with bone windowing confirm the sphenoid involvement
with stenosis of the right foramen rotundum and the vidian canal.
