Ultrasonographic and sonoelastographic features of XXXX of the salivary glands.

@entity1 @entity39 @entity5 @entity189 @entity1893 @entity5123
AIMS: The typical ultrasound features of @entity5123 are considered to be the well-defined contour, the regular, sometimes lobulated shape, homogeneous structure and poor vascularization. The goal of our study was to verify the validity of these features and to identify a typical sonoelastographic pattern for @entity5123 . @entity1 AND METHODS: Between April 2007 and February 2010, 70 salivary gland masses were examined prospectively (58 in the parotid gland, 12 in the submandibular gland). The following features were targeted: size, limits, contour, structure, echogenicity, vascularization, elasticity/stiffness. RESULTS: Of the 70 @entity5 , 32 (45.7%) were @entity5123 , 12 (17.1%) Warthin @entity5 , 9 (12.8%) other @entity5 , 13 (18.5%) primary @entity5 , 3 metastases from @entity189 , and 1 @entity1893 . Among @entity5123 , 15 (46.9%) were inhomogeneous, 7 (21.9%) contained @entity39 areas and 14 (43.7%) were well-vascularized. The lobulated contour was identified in 14 @entity5123 (43.7%), no other @entity5 presented this type of contour, but it was identified in 2 @entity5 (15.3%). On sonoelastography, most @entity5123 were heterogeneous. The elastic component represented more than 50% of the @entity5 tissue in 22 cases (68.7%). This aspect was also identified for 6 @entity5 (46.1%). CONCLUSIONS: Our results demonstrate that features such as heterogeneous structure, rich vascularization and intra-tumoral @entity39 may be identified in a significant number of @entity5123 . The most specific element in our group was the presence of a lobulated contour, which was not seen in any other @entity5 , but may rarely appear in certain @entity5 . The elastographic aspect was heterogeneous for most @entity5 , but the elastic composition identified in most @entity5123 was also present in a significant proportion of @entity5 . Therefore, a typical sonoelastographic pattern for @entity5123 could not be identified.
