case_images: Contrast-enhanced computed tomography head with bone window (a-c) demonstrating well-defined, lytic, sharply marginated intradiploic lesion marked with an arrow in the left sphenotemporal region reaching up to orbit and sphenoid sinus medially. Bony shell (arrow) is seen all around the lesion

case_images: Bone window of CT scan further demonstrated the intradiploic nature of the lesion [Figure 1a-c].

case_images: On magnetic resonance imaging (MRI), the lesion was hypointense on T1-weighted, hyperintense on T2-weighted sequences, and demonstrated homogenous enhancement after gadolinium administration [Figure 2].

case_images: The underlying temporal lobe and dura were seen buckled under pressure but were not involved by tumor [Figure 3].
