Infantile recurrent sialectatic parotitis: the role of sonography and sialography in diagnosis and follow-up.

The results of a clinical, sonographic and sialographic study in 10 children (aged 4-10 years) with recurrent sialectatic parotitis are presented. Alteration in the sonographic pattern of the parotid glands, consisting of multiple hypoechogenic areas in the parenchyma, were found in four cases; milder nonhomogeneity was seen in four cases, and an almost normal pattern in two cases. Sonographic follow-up in two children showed a parallel reduction in non-homogeneity with symptomatic improvement. A probable therapeutic action following sialography using fat-soluble contrast medium was observed in four of the 10 children. The familial nature of the disease, which has not previously been described, is documented.
