FIG 4. Axial (A)and coronal (B) CT images demonstrate a hyperattenuated mass eroding the roof of the glenoid fossa, abutting the Eustachian tube, and remodeling the mandibular condyle. Sagittal T2-weighted MR image (C) reveals the mass of low signal intensity (arrows) centered within the TMJ anterior to high signal intensity of fluid within the mastoid air cells (TR/TE/NEX = 3000/100/2). Diffusion-weighted image (D) demonstrates restricted diffusion. Axial (E) and coronal (F) contrast-enhanced T1-weighted images reveal a large lobulated mass eroding the squama, extending into the middle cranial fossa, with a superficial rim of enhancement (TR/TE/NEX = 600/20/2)
