If two buds of pancreas do not fuse, the anomaly is
## **Core Concept**
The pancreas develops from two distinct buds (dorsal and ventral) that fuse during embryonic development. Failure of these buds to fuse results in pancreatic anomalies.
## **Why the Correct Answer is Right**
The correct answer, **D. Pancreas divisum**, occurs when the dorsal and ventral pancreatic buds fail to fuse during embryonic development. In pancreas divisum, the pancreas drains through a minor papilla (or accessory papilla) rather than the major ampulla of Vater. This anomaly is usually asymptomatic but can be associated with pancreatitis.
## **Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify a known pancreatic anomaly related to developmental failure of pancreatic buds fusion.
* **Option B:** This option is incorrect because it also does not specify a recognized anomaly related to the failure of fusion of the pancreatic buds.
* **Option C:** This option is incorrect as it does not describe a known anomaly resulting from the failure of pancreatic buds to fuse.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that **Pancreas divisum** is a congenital anomaly that can be a cause of recurrent pancreatitis. It's diagnosed with imaging techniques like ERCP or MRI.
## **Correct Answer:** D. Pancreas divisum
