[Role of diagnostic imaging in chronic recurrent parotitis in childhood]
1Klinik und Poliklinik für Hals-, Nasen- und Ohrenkranke, Klinikum Grosshadern, Ludwig-Maximilians-Universität München.
Background:
Chronic recurrent parotitis represents a disease of still uncertain etiology that can be divided into a childhood and an adult form. Sialography is still the imaging procedure of choice.
Method:
We report about a nine-year-old girl who had had six episodes of parotitis in the past two years. MR sialography is presented as an alternative to conventional sialography. MR was performed with a 1.5 T wholebody tomograph using a high resolution 3D-CISS sequence.
Results And Conclusion:
MR sialography does not require any contrast medium. It primarily images liquid structures, and the flow of saliva can be adequately demonstrated after stimulation with ascorbic acid. These special features of MR sialography allow its use also during acute episodes of sialadenitis, thus providing a significant improvement over conventional sialography. Furthermore, no overlapping occurs as in conventional summation images, due to the multiplanar reconstruction features.
