Hi doctor,

I had a CT scan of the abdomen and pelvis with IV contrast. The radiologist report is as follows. The findings are as follows. There is a 0.9 cm cystic structure in the uncinate process, which is new since the comparative examination with the last year scan report. This should be further evaluated with endoscopic ultrasound. Cavernous hemangioma in the right hepatic lobe. Cholecystectomy. Left renal cyst and angiomyolipoma. There is no adenopathy. Mild degenerative changes in the spine and hips. The impression is new cystic structure in the uncinate process of the pancreas, maybe an IPMN. Endoscopic ultrasound is recommended for further evaluation. My doctor just scheduled an endoscopy for me. I would like to get an explanation of IPMN and the percentage that it can turn malignant. I also want to understand how a cystic structure differs from a cyst. I am 55 years old. My father died of pancreatic cancer when he was 73. My mother had a pancreatic insulinoma. Are there any specific questions that I should ask my doctor during the follow-up visit after the endoscope?



Welcome to icliniq.com. We are here to assist you. The term 'cystic structure' is synonymous with 'cyst'; a cyst is entirely encased by a wall. It's possible that your radiologist observed a structure resembling a cyst with indistinct walls. It's important to note that radiology alone may not provide the answer you seek; a pathologist's evaluation is required. To determine if the cyst or cystic structure is benign or malignant, an endoscopic biopsy is recommended. Additionally, consider having CA 19-9 levels (a tumor marker) and serum insulin levels checked. These steps will collectively provide a more comprehensive understanding of your condition.
