[Ultrasonography: a complement to sialography in recurrent chronic childhood parotitis].
The objective of this research is to compare the ultrasonographic (USG) and sialographic contributions for the diagnosis of Recurrent Parotitis in Childhood (RPC). Bilateral USG of the parotid gland was performed among 16 children with RPC and 16 healthy children. The image of the normal parotid glands was compared with the image of the parotid gland with RPC. A pathologic USG pattern for RPC was obtained which consisted in a homogeneous, micronodular parenchyme with a diffuse increase density, sometimes with multiples hypoechogenous areas, that were considered solid hypoechogenous nodules suggesting inflammatory nodes. A glandular contour finely granulated was described with normal peri-parotidareas and with aponeurotic-muscular planes. Then 16 USG of the parotid gland of the children with RPC were compared with 16 Sialography previous obtained. The possibilities of diagnosis of the disease with both techniques was not different (p > 0.05). When the clinic was correlated with the USG it was possible to obtain parameters of severity of the glandular damage and to visualise the degree of changes of the parenchyma of each child with RPC. In some cases, bilateral damage was observed in children with clinical unilateral symptoms. The USG was performed in children in the acute phase of disease, visualising the microabscess in the gland and confirming the previous diagnosis. Finally, it was possible to conclude the utility of USG in the study of the disease. Being a not invasive exam, harmless, unpainfully echography, was easily accepted by the child. Also, we obtain information not only about the diagnosis of the disease, but also about the severity, prognosis, treatment and follow-up of the infant patients.
