Abstract

Imaging can be helpful when investigating salivary gland pain and swelling. Typically in such cases, an ultrasound (US) or conventional sialogram would be requested in seeking obstructed or dilated ducts, a ductal calculus or an abscess within the gland. Occasionally a CT scan is requested. MR is usually reserved for investigating clinically palpable masses in the glands.

In acute non-obstructive parotitis, the differential diagnosis includes acute non-suppurative parotitis (as found in mumps), early Sjögren’s syndrome, or suppurative parotitis as seen following duct obstruction. Despite sometimes strong insistence on retrograde contrast sialography, this may exacerbate the pre-existing inflammatory process. The imaging of a young patient expands on these observations.
