Abstract
- Although diseases of the parotid gland are relatively uncommon in children, a variety of benign and malignant lesions may occur and the use of imaging is essential for accurate diagnosis and treatment. Ultrasonography (US) is the initial imaging modality utilized for suspected parotid lesions, and its use may suggest a correct diagnosis in an adequate clinical setting. The use of computed tomography (CT) and magnetic resonance imaging (MRI) are useful for the assessment of large and atypical lesions. These modalities also allow the ability to image the deep parotid lobe and to better define the nature of a lesion. CT is the preferred imaging modality for inflammatory processes, including suspected sialolithiasis, abscesses and salivary duct obstructions, whereas MRI is usually used to evaluate tumors due to excellent anatomic resolution and a lack of ionizing radiation exposure, especially in children. This report describes the imaging findings of various parotid gland lesions in children. Familiarity with these findings will aid in lesion characterization and should facilitate optimal clinical management.
