Orbital and extraorbital involvement before and after steroid therapy. Upper row: coronal STIR (a, b) and axial FLAIR (c) MR images before treatment. Lower row: coronal STIR (d, e) and axial FLAIR (F) MR follow-up images after steroid therapy. Evidence of marked enlargement and edema involving the lateral rectus muscle in the right orbit, with infiltration of the contiguous fat (a), and the temporal and pterygoid muscles in the ipsilateral masticator space (b), all showing complete regression at follow-up (d, e). The massive vasogenic edema of the anterior portion of the temporal lobe evident in the initial MR scan (c), also shows dramatic reduction at follow-up (f)
