Target Audience:
Intended for neuroradiologists and neuroradiology trainees with varying degrees of experience.

Learning Objective:
Recognize and give a differential diagnosis for the more common
inflammatory, congenital, and neoplastic processes that affect the pediatric parotid gland
and periparotid region.

A wide spectrum of pathologies may affect the parotid gland and periparotid region in
children. Inflammatory processes, congenital anomalies, and benign neoplasms are the
more commonly encountered entities; primary and metastatic malignancies are relatively
rare. Sonography and contrast-enhanced CT and MR imaging are the primary imaging
modalities for evaluating facial swelling in a child. We reviewed the clinical presentations
and multimodality imaging features of processes that affect this region in children and
emphasized more specific imaging characteristics that can help differentiate similar-appearing
lesions. Correlation of key clinical and imaging characteristics can allow radiologists
to provide a succinct differential diagnosis and guide appropriate therapy.
