childhood sialectasis
Juvenile recurrent parotitis (JRP) is a form of recurrent inflammatory parotitis occurring in childhood.
Epidemiology
JRP is considered the second most common cause of parotitis in childhood and commonly begins between 3 and 6 years of age.
Clinical presentation
Multiple episodes of parotid swelling and/or pain associated with fever or malaise over a period of years.
Pathology
JRP is of unknown etiology and characterized by a non-obstructive, non-suppurative nature. It can have unilateral or bilateral involvement.
Associations
The entity sometimes occurs in association with
- Sjogren syndrome
- lymphoma
- immunodeficiency states: including human immunodeficiency virus.
Radiographic features
Ultrasound
May demonstrate multiple hypoechoic areas and heterogeneous echoes within the affected parotid gland .
MRI / MR sialography
CISS sequences are thought to better demonstrate intraglandular ducts and sialectasis than HASTE images.
Treatment and prognosis
In most cases, the symptoms resolve spontaneously after puberty but in some cases can persist into adulthood.
