Anytime you see a dilated pancreatic duct, especially where there's(abrupt pancreatic ductal) abrupt cutoff with a pancreatic duct, anytime you see a dilated bile duct, anytime you see atrophic upstream pancreas, you have to be worried about the possibility of an underlying tumor.

In particular, I never let a dilated pancreatic duct go, especially when it's segmental, or when there's abrupt cutoff of the duct. Even if I don't see a tumor, that is a tumor until proven otherwise. And that patient needs another test, which is usually going to be an endoscopic ultrasound, if you can't identify the mass on CT.

Now here's a relatively classic example, right? You see a hyper dense mass. But notice the abrupt cutoff of the distal common bile duct at the level of the lesion. Even if you didn't see the mass, you would have to be worried about the possibility of an occult neoplasm based on the morphology of the duct.

【CT Imaging of Solid Pancreatic Tumors （the final part)胰腺实性肿瘤的CT表现】
任何时候，当我们看到扩张的胰管（特别是突然截断的征象）、扩张的胆管、（胰液逆流？这里不太确定）时，我们都要考虑有潜在的肿瘤隐患。
尤其是，我从来不放过一例胰管扩张的患者，特别是节段性扩张或突然截断。即使我没看到肿块，也会考虑是肿瘤性病变，直到其被证实不是肿瘤。那么患者就需要其他的检查，若在CT上不能证实肿块，通常需行内镜超声。
这是一例相对典型的病例，是吧？可见稍高密度肿块。但在病变的平面，可见胆总管远端突然截断的征象。即使我们没看到肿块，可要根据胆管的形态，考虑隐匿性肿瘤的可能性。
