Solid XXXX of the pancreas: Findings from routine screening sonographic examination and the value of contrast-enhanced ultrasound.

@entity5 @entity1
BACKGROUND: Solid @entity5 (SPTs) are rare neoplasms of the pancreas. We describe the features of these small @entity5 identified on routine screening sonographic (US) examination and the potential value of using contrast-enhanced ultrasound (CEUS) scanning. METHODS: We retrospectively reviewed records from 17 @entity1 who had undergone screening via US examination at Peking University Third Hospital between January 2000 and June 2011. Each of these @entity1 had been confirmed by a pathologist to have an SPT. Six @entity1 had undergone CEUS prior to surgery. We recorded all features on both gray-scale US and CEUS. RESULTS: All @entity1 (4 @entity1 and 13 @entity1 ; ages 23-35 years; mean age, 27.2 years) were initially screened by US. The largest mass identified was 5.0 cm in diameter (mean diameter, 4.2 cm), and most @entity5 showed homogeneous hypoechogenicity. A hyperechoic rim was detected in four masses. CEUS showed peripheral-rim hyperenhancement in the arterial phase of all six masses. CONCLUSIONS: Routine screening US examinations are capable of identifying small (<5.0 cm) SPTs. These screening examinations allow diagnosis on the basis of typical imaging features, such as a homogeneously hypoechoic mass with a hyperechoic rim. CEUS shows greater detail of the rim and cystic areas in the @entity5 , which significantly improves the proper diagnosis.    2014 Wiley Periodicals, Inc. J Clin Ultrasound, 2014.
