Abstract

PURPOSE:

Chronic recurrent parotitis (CRP) is a rare inflammatory disease characterized by multiple episodes of unilateral or bilateral parotid inflammation over a period of years. The objective of this study was to evaluate the parotid glands using MRI during acute inflammation as well as during symptom-free intervals.

METHOD:

Twelve children with a history of CRP were included. Four patients were examined during the acute phase and eight children during symptom-free intervals. MR findings were correlated with the clinical status.

RESULTS:

Two different patterns were identified by MRI: acute inflammation versus chronic inflammation. Contrast enhancement of the parotid gland indicated acute inflammation. Cysts due to chronic inflammation were encountered in children who suffered multiple episodes of inflammation.

CONCLUSION:

Our findings suggest that CRP is characterized by recurrent, acute exacerbations of inflammation, resulting in a slowly progressive destruction of the parotid gland.
