Computed tomography and magnetic resonance imaging in pediatric salivary gland diseases: a guide to the differential diagnosis

Pediatr Radiol. 2020 Aug;50(9):1293-1307. doi: 10.1007/s00247-020-04684-3. Epub 2020 Jun 18.

Abstract

Salivary gland pathologies in children are frequent, particularly viral infections, but rarely need cross-sectional imaging. However, when a mass involves the salivary spaces (primarily or as a secondary invasion from other neck spaces) it may pose problems in the differential diagnosis and in immediate management. Infrequently, systemic autoimmune diseases can also involve the salivary parenchyma in children and correctly interpreting the constellation of findings in the whole body is critical for the diagnosis. Distinguishing between cystic and solid masses is the first step for radiologists in order to narrow down the diagnosis. Location and spatial extension are the most important elements differentiating cystic masses, while signal characteristics, internal structure and local invasion help in the differential diagnosis of solid masses.
