Radiologic Findings


Ultrasonographic images show a large, soft tissue mass of heterogeneous echogenicity (Figs. 24A and 24B). Color Doppler evaluation shows high flow and high vessel density (Fig. 24B). MRI including axial unenhanced T1-weighted image (Fig. 24C), coronal fat-suppressed T2-weighted image (Fig. 24D), and fat-suppressed T1-weighted image following gadolinium enhancement (Fig. 24E) show a large mass initially isointense to muscle within the right parotid gland extending to the right parapharyngeal region with multiple internal flow voids. The lesion shows high T2 signal intensity and intense enhancement following gadolinium administration.
