I wrote about my history and results of a CT scan a few days ago - the CT scan showed the presence of a hypodense lesion with signs of acute pancreatitis and an enlarged retroperitoneal lymph node (10 mm). The radiologist diagnosed the lesion as a pancreatic pseudocyst, but suggested further imaging to rule out cystic neoplasms. I went to a GI specialist at a leading University hospital, who looked at the images and concurred with the view of the radiologist. The GI physician recommended follow up imaging, both an MRCP and an EUS. I had an MRCP on Friday. The impression is as follows (I am paraphrasing the words): There is a 3 x 2 cm cystic lesion slightly superior to the body of the pancreas. There is no pancreatic ductal dilatation. There is a communication between the cyst and the pancreatic duct via a side branch. The pancreas is slightly enlarged, heterogenous in appearance with some restricted diffusion. Findings are suggestive of acute pancreatitis. The retroperitoneal lymph node is enlarged (1.3 x 1 cm). Final impression is strongly suggestive of a pancreatic pseudocyst.
Would this additional evidence from the MRCP help rule out cancer? Or, do I have to wait for the EUS for conclusive proof?
