Abstract
Extraocular muscle enlargement can result from a wide variety of disease processes. Although observations of the pattern of muscle involvement, muscle shape and enhancement, superior ophthalmic vein and cavernous sinus enlargement, sinus and bony wall abnormalities, and proptosis can lead to a limited differential diagnosis in some cases, no radiographic finding in itself seems to be pathognomonic. Correlative clinical findings are necessary to make a secure diagnosis.
