Juvenile polyposis syndrome (JPS) may coexist with hereditary hemorrhagic telangiectasia (HHT) due to implication of the SMAD4 gene in a subset of both diseases. To the best of our knowledge, we present the first case in the radiologic literature on the MRI findings in a patient with this rare combined diagnosis undergoing workup for burden of disease., (Copyright © 2018 Elsevier Inc.

Xanthogranulomatous pancreatitis (XGP) is an extremely rare cause of a cystic pancreatic mass. The pathophysiology of this process is not entirely clear but likely results from a combination of duct obstruction, infection, and repeated hemorrhage. It is difficult to differentiate this inflammatory lesion from a cystic neoplasm and, therefore, in the majority of cases XGP is misdiagnosed as a neoplasm on preoperative imaging. In this report, we describe a case of XGP, the imaging characteristics of XGP, and a differential diagnosis for a cystic pancreatic lesion., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Ciliated foregut cysts are extremely uncommon pancreatic cystic lesions, with-to the best of our knowledge-only five cases previously reported in the English literature. We report herein on a case of a ciliated foregut cyst of the pancreas connected with the duct of Wirsung. The magnetic resonance imaging, endoultrasonographic, and cytologic features are described and a brief review of literature is also presented., (Copyright © 2015 Elsevier Inc. All rights reserved.)

The "peripheral washout sign" is a magnetic resonance imaging finding defined as an enhancing liver lesion with a peripheral rim of de-enhancement relative to its center and surrounding parenchyma on delayed contrast-enhanced images. The "peripheral washout sign" has been described solely in malignant liver lesions. We present a histologically proven benign hepatic angiomyolipoma showing the "peripheral washout sign". To the best of our knowledge, this is the first report on a benign hepatic lesion exhibiting this extremely specific imaging feature., (Copyright © 2015 Elsevier Inc. All rights reserved.)
