Fig. 2. Axial and coronal T2-weighted (A, D), T1-weighted (B, E), and gadolinium-enhanced T1-weighted (C, F) images show a heterogeneously enhancing lesion with extension into the orbit, masticator space, and middle cranial fossa and proptosis of the right eye. Enhancement and edema are also noted within the masticator muscles and surrounding soft tissue. Nonenhancing parts of the lesion with low T2 signal intensity probably represent dense fibrosis identified on the histologic examination.
