 So sometimes the cases not are easy. They can be sometimes very challenging. And in this particular case, we are seeing multiple cystic legion in the pancreatic head. They do not qualify to be called as bunch of grapes, but they are multiple. They're situated together. They are packed together each other and confined to the pancreatic head. And then we see similar kind of findings along the incident process on the backside. But in addition of that, we see a dilated pancreatic duct, which shows kind of normal tapering, as we expect in the body and tail, but it becomes more prominent in the pancreatic head. And as we follow this particular pancreatic duct in the pancreatic head towards the major papilla, it becomes very small. So let's see how it looks on the coronal. On the coronal, we follow this pancreatic duct from the pancreatic tail. It gradually increases in size, as we expect in a normal pancreas, because duct is usually bigger in the pancreatic head and becomes smaller as we go from body to tail. So it shows normal tapering there, but as we go forward towards the pancreatic head, we see this duct just disappears or narrow. And then it is associated with some more cystic legions in the pancreatic head. One of them possibly has a communication with the main pancreatic duct. So it can be a mixed type of IPMN here, but we don't know what exactly going on. It is just an IPMN side branch or it is main duct IPMN, together with the side branch IPMN. So question is, what else it could be? Can this be a case of pancreatitis, which is called as obstructive chronic pancreatitis, which is causing obstruction of the opening of the main pancreatic duct near the major papilla? That is another possibility here. So let's see how it looks on the other images. So remember one thing, the sign we have discussed before, that is duct penetration sign. If we see that penetrating duct through the area of possible mass, then it's possibly benign. So in this particular case, on these thin images, we see the duct is present here, and that drains towards the major papilla. Let's see how it looks on post-contrast images, because post-contrast images are thin 3 millimeter images, and sometime the duct is better seen on those images. And as we follow this up, we see the duct actually very clearly here. So duct is opening and communicating with the directed duct. The lesion or pseudo mass we have in the pancreatic head is causing focal structure in the proximal pancreatic head, leading to distal ductal dilatation. This mimics like it is possibly mixed duct IPMN, but seeing the entire duct, passing through the so-called lesion, gives you a confidence that it is not cancer at least. And secondly, we do not have any other signs of the cancer here, because we are seeing the parenchyma as well maintained. We are not seeing any tissue going outside. The boundaries of the pancreas, none of the vessels are involved, and there is no haziness surrounding the vessels. We can go back and look on arterial face one more time, and find everything is okay there. So all of the vessels are looking fine. What about the SMV? SMV is also well maintained. It is well maintained throughout in size and caliber and shape. There is no distortion. So this cannot be a mass, first of all. It is not a pancreatic head mass. The question whether it is obstructive chronic pancreatitis, or it is an IPMN with side branch IPMN coexisting with that. So these are the two differential here. And the next step will be either follow-up with the MR, surveillance, or a biopsy. So in this particular case, I would not prefer biopsy because I do not see any signs of cancer anywhere. Follow-up is a good advice here. Surveillance will be better, because the chances that it's going to be most likely chronic obstructive pancreatitis is higher because of this duct penetration sign, which we have seen on post-contrast images.
