case_images: External examination showed significant proptosis and downward displacement of the left eye [Figure 1].
case_images: (a) MRI, coronal view of a heterogeneous intermediate signal (white arrow) of the left superior orbital mass, infiltrating the superior rectus muscle. (b) The transverse view of the same heterogeneous mass (black arrow) displacing the globe anteriorly (proptosis).
