Ultrasound of Parotitis Radiology Lectures | Radquarters

- Medicine
In this radiology lecture, we review the ultrasound appearance of parotitis in the pediatric population!
Key teaching points include:
* Parotitis = Inflammation of the parotid glands
* Acute parotitis is usually infectious, most commonly viral
* Mumps is most common viral cause in children, often bilateral
* Bacterial parotitis can cause suppurative parotitis seen in premature infants and immunosuppressed children
* Acute parotitis on US: Enlarged, heterogeneous, hyperemic gland(s) +/- lymphadenopathy
* Since can be bilateral, comparison scanning essential
* Bacterial parotitis may be complicated by abscess
* “Pomegranate sign” may be seen in setting of acute parotitis: Uniform anechoic foci scattered throughout the gland
* Juvenile recurrent parotitis (JRP) = Recurrent inflammatory parotitis in children of unknown etiology
* JRP is rare, but second most common cause of parotitis in childhood after mumps
* JRP often begins between age 3-6, typically resolves spontaneously after puberty
* Usually idiopathic, JRP can be presenting symptom of Sjogren’s syndrome, lymphoma, and underlying immunodeficiency
* JRP on US: May be unilateral or bilateral, multiple hypoechoic foci of salivary secretions scattered throughout the gland +/- central calcifications, color Doppler can be normal
* Additional causes of parotitis: Sialolithiasis/obstruction, autoimmune (Sjogren syndrome, chronic sclerosing sialadenitis), infectious (HIV, TB), and sarcoidosis (rare in children).
