Fat-suppressed T1-weighted gadolinium-enhanced axial scans through the skull base (a, b), and T1-weighted gadolinium-enhanced axial scans of the skull base (c, d). There is bilateral maxillary sinusitis and an infiltrative lesion of the right retropharynx (circle) around the internal carotid artery (arrow).
