Figure 5: A 59-year-old man with a history of chronic sialadenitis of the left parotid gland. (a) Lateral digital subtraction sialogram shows multiple strictures, sialectasis, and prestenotic dilatation of the Stensen duct (arrows) and also of secondary and tertiary branching intraglandular ducts (arrowheads). (b) Lateral MR sialogram shows the same abnormal findings but at lesser spatial resolution. Subtle strictures are more difficult to visualize and sialectasis is not as prominent (arrow). The enlargement of the ductal system is demonstrated up to secondary branching ducts [16].
