Purulent obstructive sialadenitis of the submandibular gland. Axial (a) and coronal (c) post-contrast fat-suppressed T1-weighted images show a dilated submandibular duct (Wharton’s duct) (arrow), and significant edema in and around the gland (dotted arrow). ADC map confirms that the dilated duct is filled with pus (arrow) (b), and axial T1-weighted imaging at a level slightly superior shows a sialolith as an ovoid area of signal void (arrow) (d)
