Figure 2 Initial CT scans, showing the involvement of the infraorbital region of the lesion (A) Axial CT scan with soft tissue window: visualization of orbital cavity involvement causing compression with a displacement of the inferior rectus muscle of the right eyeball. (B) CT in sagittal section with hard tissue window: slightly hyperdense image with expansion to the inferior wall of the orbit, invasion of the right maxillary sinus, and involvement of the sphenoid bone. (C) Coronal CT scan with hard tissue window: involvement of the infraorbital region.
