Gallbladder Tumors

Ioan Tiberiu Tofolean* and Mihaela Țanco

Abstract

Conventional ultrasound (US) is the most important and fundamental imaging method for gallbladder diseases. Biliary disorders are still very common nowadays, especially the ones affecting the gallbladder. Either benign (in most cases), or malignant, their diagnosis still relies on the abdominal ultrasound. Gallstones and their complications represent a major public health issue in Europe and other developed countries, and affect > 20% of the population. According to GLOBOCAN 2020 data, gallbladder cancer is the 23rd most incident, but the 20th most deadly cancer worldwide, which could be explained by the late discovery of gallbladder cancer. Worldwide, gallbladder cancers represented 0.6% of the total cancer cases in 2020, with a mortality of 0.85% among all cancers. US becomes more appropriate than computed tomography (CT) and magnetic resonance imaging (MRI) for the detection of gallbladder diseases, having the advantages of safety (without radiation), real-time imaging, considerable cost effectiveness and high spatial resolution. Regardless of the previously mentioned advantages, the accuracy and sensitivity of US are not satisfactory, particularly when gallstones or other gallbladder lesions occupy the entire gallbladder lumen. Contrast-enhanced ultrasound (CEUS) is considered to increase the diagnostic precision of US.
