Core Tip

Core Tip: We report the case of a 45-year-old man with intrahepatic biliary cystadenoma (IBC), which infrequently manifests as a monolocular cystic structure because of the lack of intracystic septa. This case was diagnosed by imaging examinations, especially contrast-enhanced ultrasound. Herein, we have summarized the characteristics of contrast-enhanced ultrasound performance for IBC to achieve a more accurate diagnosis. Moreover, it is worth noting that the lack of intracystic septa in this case cannot be regarded as imaging evidence to exclude IBC.
