Figure 2. Initial radiographic examinations. CT (axial cross-section). (A) Soft tissue window shows a discreet extension of the lesion to the superficial tissues in the medium bottom from the right orbit. (B) Bone window shows erosion of the bone structure and presence of a continuous solution in the walls of the maxillary sinus, ethmoidal intercellular septum, sphenoidal sinus wall and frontal sinus, notably, in the medium and top walls from the right orbit. (C) CT from sagittal and frontal cross-section: soft tissue window shows extension of the lesion to the paranasal sinuses, the nasal cavity bilaterally, and involvement of the right orbit cavity. (D) Volumetric reconstruction illustrating the tumor extension.
