Meningioma (sphenoid wing - en plaque)


This patient presented with proptosis on the right and has imaging features characteristic of a sphenoid wing en plaque meningioma.  There is little differential, however (depending on the age) fibrous dysplasia, Paget's disease of bone and a sclerotic metastasis should be considered. 

This case was subsequently histologically confirmed as being a meningioma.
