英文摘要:

BackgroundSolid pseudopapillary tumors (SPTs) are rare neoplasms of the pancreas. We describe the features of these small tumors identified on routine screening sonographic (US) examination and the potential value of using contrast-enhanced ultrasound (CEUS) scanning.

MethodsWe retrospectively reviewed records from 17 patients who had undergone screening via US examination at Peking University Third Hospital between January 2000 and June 2011. Each of these patients had been confirmed by a pathologist to have an SPT. Six patients had undergone CEUS prior to surgery. We recorded all features on both gray-scale US and CEUS.

ResultsAll patients (4 men and 13 women; 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 tumors showed homogeneous hypoechogenicity. A hyperechoic rim was detected in four masses. CEUS showed peripheral-rim hyperenhancement in the arterial phase of all six masses.

ConclusionsRoutine 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 tumor, which significantly improves the proper diagnosis. (c) 2014 Wiley Periodicals, Inc.
