case_images: Computed tomography (CT) imaging of the head performed in the emergency department demonstrated a large focus of edema involving the right temporal lobe as well as hyperdense dural thickening in the right medial petrous apex with 6 mm of midline shift (Figure 1).
case_images: T1-weighted magnetic resonance imaging (MRI) of the head demonstrating abnormal signal along the dural surface of the right medial petrous region (smaller arrow) and paraclinoid region as well as sphenoid bone and cavernous sinus with upper sphenoid tumor extension (larger arrow), also extending to the foramen ovale and into the upper margins of the right infratemporal fossa.
