Uncommon Intraluminal Tumors of the Gallbladder and Biliary Tract: Spectrum of Imaging Appearances.

Radiographics 2019 Feb 1:180164. Epub 2019 Feb 1.

From the Departments of Radiology (A.C., C.L.V., P.N., N.A.H., V.Y., F.H.M.) and Pathology (A.J.B., G.Y.Y.), Northwestern Memorial Hospital, Northwestern University Feinberg School of Medicine, 676 N St. Clair St, Suite 800, Chicago, IL 60611; Department of Radiology, Emory University School of Medicine, Atlanta, Ga (P.K.M.); and Department of Radiology, Mayo Clinic, Scottsdale, Ariz (C.O.M.).

Intraluminal pathologic conditions of the bile ducts and gallbladder are common, most frequently consisting of calculi and adenocarcinoma. In recent years, intraductal papillary neoplasm of the bile ducts (IPN-B), which is analogous to intraductal papillary mucinous neoplasm of the pancreas, has been recognized as a distinct pathologic entity and a precursor lesion to adenocarcinoma of the bile ducts. Intraductal tubulopapillary neoplasm (ITPN) of the bile duct was subsequently described as a distinct pathologic entity. Read More

Comparison of DWIBS/T2 image fusion and PET/CT for the diagnosis of cancer in the abdominal cavity.

Exp Ther Med 2017 Oct 22;14(4):3754-3760. Epub 2017 Aug 22.

Department of Neurosurgery, National Hospital Organization Shimoshizu Hospital, Yotsukaido, Chiba 284-0003, Japan.

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively. Read More

Contrast-enhanced ultrasound in gallbladder disease: a pictorial review.

Abdom Radiol (NY) 2016 08;41(8):1640-52

Department of Radiology, The Royal Melbourne Hospital, Grattan Street, Parkville, VIC, 3050, Australia.

With its excellent contrast and spatial resolution, and the ability to image in real-time, ultrasound is the main imaging modality for assessing the gallbladder (GB). The application of contrast-enhanced ultrasound (CEUS) of the GB is now increasingly recognized as a useful addition to ultrasound and other cross-sectional imaging in the assessment of neoplastic and non-neoplastic GB disease. With the ability to image microcirculation and optimal contrast resolution, CEUS allows high-quality delineation in real-time, allowing for increased diagnostic confidence. Read More

Pancreatic cysts in general population on ultrasonography: Prevalence and development of risk score.

J Gastroenterol 2016 Dec 17;51(12):1133-1140. Epub 2016 Mar 17.

Department of Clinical Laboratory, The University of Tokyo Hospital, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-8655, Japan.

Background: Pancreatic cysts are related to the presence of ductal adenocarcinomas elsewhere in the pancreas, and are also associated with an increased risk of pancreatic adenocarcinoma in the future. Most of the previous studies that investigated the prevalence of pancreatic cysts focused on patients within a hospital or out-patient setting, which may not be representative of the general population. We investigated the prevalence and predictive factors for the presence of pancreatic cysts within a large number of subjects via general health examination. Read More

The gallbladder: uncommon gallbladder conditions and unusual presentations of the common gallbladder pathological processes.

Abdom Imaging 2015 Feb;40(2):385-99

Department of Radiology, Yale School of Medicine, 20 York St, New Haven, CT, 06510, USA,

This article reviews a spectrum of gallbladder conditions that are either uncommon or represent unusual manifestations of common diseases. These conditions are divided into four major categories: (a) congenital anomalies and normal variants including duplication, ectopia, and lymphangioma; (b) inflammatory processes and stone-related diseases and complications including adenomyomatosis, emphysematous cholecystitis, xanthogranulomatous cholecystitis, gangrenous and hemorrhagic cholecystitis, perforation, gallstone ileus, and Bouveret and Mirizzi syndromes; (c) gallbladder neoplasms including adenocarcinoma with associated porcelain gallbladder, squamous cell carcinoma, lymphoma, melanoma, and neurofibroma. A thorough understanding of the imaging characteristics of each condition can help the radiologist to make a timely and accurate diagnosis, thus avoiding potentially harmful delays in patient management and decreasing morbidity and mortality rates.

Multidetector computed tomography diagnosis of adenomyomatosis of the gallbladder.

Turk J Gastroenterol 2013 ;24(3):286-9

Türkiye Yüksek İhtisas Hospital, Department of Radiology, Ankara, Turkey.

The differentiation of gallbladder adenomyomatosis from gallbladder carcinoma is important as both conditions may present with thickening of the gallbladder wall or as a focal mass. Identification of Rokitansky-Aschoff sinuses is the key feature in making an accurate diagnosis of gallbladder adenomyomatosis on imaging studies. The diagnosis of gallbladder adenomyomatosis can be made with accurately by multidetector computed tomography when the presence of Rokitansky-Aschoff sinuses (small cystic spaces within the thickened gallbladder wall) are noted.
