Ultrasound Registry Review (URR) Abdomen Practice Exam

A cluster of grape-like cysts describes the microcystic pattern of serous cystadenoma. These pancreatic lesions are made up of numerous tiny cysts, often less than a couple of centimeters, which together create a honeycomb or grape-like appearance on ultrasound and cross-sectional imaging. They’re usually benign and can show a central scar that may calcify. The other possibilities don’t fit this pattern: mucinous cystadenomas tend to have fewer, larger cysts with thicker walls and carry malignant potential; pseudocysts are solitary fluid collections arising after pancreatitis and lack multiple small cysts; and pancreatic adenomas aren’t characterized by this grape-like microcystic cluster.
