Chronic Pancreatitis or Pancreatic Tumor? A Problem-solving Approach

Area of Science:

• Radiology
• Gastroenterology
• Oncology

Background:

• Inflammatory pancreatic abnormalities can mimic pancreatic ductal adenocarcinoma on imaging.
• Accurate preoperative diagnosis is often precluded, potentially leading to unnecessary surgeries.

Purpose of the Study:

• To review secondary imaging features that help differentiate inflammatory pancreatic masses from malignant lesions.
• To improve diagnostic accuracy and reduce unnecessary surgical interventions.

Main Methods:

• Review of imaging findings in inflammatory pancreatic conditions.
• Identification and analysis of secondary imaging signs suggestive of inflammation versus malignancy.

Main Results:

• Specific signs like the duct-penetrating sign, skip strictures, and vessel displacement can indicate inflammatory processes.
• Other signs such as capsulelike rim and displaced calcifications are also discussed.

Conclusions:

• Awareness of secondary imaging signs aids radiologists in differential diagnosis.
• Distinguishing inflammatory from neoplastic lesions is crucial for appropriate patient management and avoiding unnecessary surgery.
