To describe the imaging features of serous neoplasms of the pancreas using ultrasound, endoscopic ultrasound, computed tomography and magnetic resonance imaging.
This multicenter international collaboration enhances a literature review to date, reporting features of 287 histologically confirmed cases of serous pancreatic cystic neoplasms (SPNs).
Female predominance is seen with most SPNs presenting asymptomatically in the 5th through 7th decade. Mean lesion size was 38.7 mm, 98% were single, 44.2% cystic, 46% mixed cystic and solid, and 94% hypoechoic on B-mode ultrasound. Vascular patterns and contrast-enhancement profiles are described as hypervascular and hyperenhancing.
The described ultrasound features can aid differentiation of SPN from other neoplastic lesions under most circumstances.
Core tip: Serous pancreatic cystic neoplasms are infrequent neoplasms of the pancreas. Ultrasound features including single cystic or mixed cystic and solid hypoechoic lesions, hypervascular and hyperenhancing profiles as described can aid differentiation from other neoplastic lesions under most circumstances.
