Pancreatic Lesions Misdiagnosed as Adenocarcinoma Due to Imaging Findings

Purpose: To present imaging investigation of neoplastic, inflammatory and benign pancreatic lesions as well as non-pancreatic processes that can simulate pancreatic adenocarcinoma. Materials and methods: One hundred and forty five patients were examined by CT investigation in purpose to present pancreatic lesions witch previously suspected on other diagnostic methods of imaging. Results and discussions: Adenocarcinoma of the pancreas (ACP) is one of the most aggressive malignances - leading cause of cancer-related deaths in the Western world. Focal fatty infiltration is usually most pronounced in the head of the pancreas and at contrast enhancement in CT usually appears as a region with reduced contrast material compared to normal pancreatic tissue simulating PA. Imaging of a hypoattenuating lesion in the head of the pancreas corresponds to adenocarcinoma in most cases. Conclusion: However radiologists should be careful, because a false positive diagnosis can lead to unnecessary surgery, which is not without complications.
