Pseudoaneurysm with rupture in pancreatic pseudocyst wall as demonstrated by computed tomography.
In chronic pancreatitis, inflammation originating in the pancreas may produce walled-off collections of fluid referred to as pseudocysts. This same histolytic process can also erode into adjacent arteries producing pseudoaneurysms that may hemorrhage secondary to rupture. The most common angiographic finding in patients bleeding secondary to pancreatitis is rupture of a pseudoaneurysm. We present a case of this condition that was first discovered incidentally by computed tomography during evaluation of a right renal carcinoma.
