Computed tomography (upper) showing left sphenoid sinus affected by bone remodeling and destruction of its boundaries, which resulted in possible extension of the brain. Magnetic resonance imaging (lower) shows erosion of the sphenoid sinus wall with further extension into the anterior cranial fossa, causing dural thickening and enhancement with intact optic nerve.

Computed tomography (CT) of the paranasal sinuses showed that all were opacified by a hyperdense lesion, with the left sphenoid sinus affected by bone remodeling and destruction of its boundaries, which resulted in the extension of the lesion to the brain parenchyma, the posterior part of the left rectus gyrus, the left cavernous sinus, the left internal carotid artery, and the left part of the sellar and suprasellar regions (Figure 1). Magnetic resonance imaging (MRI) of the brain and paranasal sinuses reported erosion of the sphenoid sinus wall, with further extension into the anterior cranial fossa, causing dural thickening and enhancement (Figure 1).
