Localized Bilateral Superior and Inferior Orbital Neurofibroma in the Absence of Neurofibromatosis

Figure 1

(a) Coronal MRI T2-weighted imaging showed bilateral hyperintense well-defined extraconal masses in the anterosuperior margin of both orbits (yellow arrows) (the greater one on the right side) corresponding to the supraorbital nerves. There was also another extraconal mass in the anteroinferior margin of the right orbit related to the infraorbital nerve, with similar appearance, and smaller on the left side (red arrows). (b) Growth of lesions in the left orbit (white arrows). (c) MRI axial T1-weighted imaging demonstrated the right anterosuperior tumor with isointensity relative to muscle with a fusiform morphology (orange arrow). (d) Intraoperative image of the lesion (blue arrow).
