The exact pathogenesis of gallbladder adenomyomatosis is still lacking and some controversies over its diagnosis and treatment exist. Originally recognized as a precancerous lesion, adenomyomatosis is currently recognized by recent studies as a benign alteration of the gallbladder that is often associated with cholecystitis and cholecystolithiasis. Gallbladder carcinoma is an extremely malignant disease with a 5-year survival rate of less than 5%. Read More

Few things in radiology are "pathognomonic" in their appearance or presentation. However, having an awareness of those findings which are specific to a certain entity is important when interpreting imaging studies. These classic findings can be identified with many imaging modalities, but no modality provides as many recognizable observations as an MRI. Read More

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

Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis characterized by xanthogranulomatous inflammation of the gallbladder. Intramural accumulation of lipid-laden macrophages and acute and chronic inflammatory cells is the hallmark of the disease. The xanthogranulomatous inflammation of the gallbladder can be very severe and can spill over to the neighbouring structures like liver, bowel and stomach resulting in dense adhesions, perforation, abscess formation, fistulous communication with adjacent bowel.

Background: Gall bladder cancer (GBC) is the most common and aggressive malignancy of the biliary tract with extremely poor prognosis. Radical resection remains the only potential curative treatment for operable lesions. Although laparoscopic approach is now considered as standard of care for many gastrointestinal malignancies, surgical community is still reluctant to use this approach for GBC probably because of fear of tumor dissemination, inadequate lymphadenectomy and overall nihilistic approach.

Background: Adenomyomatosis of gallbladder is an acquired hyperplastic lesion, characterized by focal or diffuse thickening of the gallbladder with intramural cysts or echogenic areas with comet tail on ultrasonography. But in some cases, especially in the localized fundal type of adenomyomatosis, the intramural anechoic cystic spaces are uncertainty which causes difficult to differential adenomyomatosis from GB cancer. The purpose of this study was to determine the accuracy of real-time contrast-enhanced ultrasonography(CEUS) in the diagnosis of the fundal localized type of gallbladder adenomyomatosis. Read More

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.
