Navigation-Guided Endoscopy Combined with Deep Lateral Orbitotomy for Removal of Small Tumors at the Lateral Orbital Apex

Figure 2

Computed tomography (CT) and magnetic resonance imaging (MRI) of the patient with schwannoma at the apex. (a, b) Orbital CT images showed a suborbicular and well-defined mass with isodensity mass located at the right inferolateral apex. (c) MRI T1-weighted images showed an isointensity mass at the right apex. (d) MRI T2-weighted images showed a high-intensity mass (white arrows).
