Acute pancreatitis secondary to migration and impaction of intragastric balloon.

Obesity represents a significant global health problem, and reducing its alarmingly high incidence is an urgent challenge. The intragastric balloon is a safe and effective device for weight loss; therefore, it is widely used. Although the frequency of serious complications resulting from its use is low, it is not exempt from them. We would like to present a case of a severe but infrequent complication secondary to this device, with the aim of highlighting the most appropriate procedure in such cases and emphasizing the importance of awareness regarding it.

Spectral CT as a method for identifying radiolucent gallstones.

We present the case of an 82-year-old woman with history of right colon adenocarcinoma in whom a routine control scan is performed using a dual-layer detector spectral CT scanner. Conventional CT scan images show a dilated cystic bile duct with no apparent cause of obstruction, finding also no lithiasis inside the gallbladder. Non-calcified gallstones are composed mainly of cholesterol and can have the same radiographic density as bile, making them hard or impossible to spot on conventional CT.
