If a pancreatic lesion remains indeterminate on CT, which action is recommended?

• A. No further imaging
• B. Immediate surgery
• C. Observation only
• D. Advise additional imaging to characterize the lesion

Answer: (D)

When a pancreatic lesion is indeterminate on CT, the next step is to obtain additional imaging to characterize the lesion. CT provides good anatomy but limited tissue characterization, so an indeterminate finding benefits from more detailed imaging to differentiate cystic versus solid lesions, assess ductal involvement, mural nodules, or vascular invasion. MRI with contrast (often including MRCP for ductal assessment) offers superior soft-tissue contrast and better delineation of pancreatic parenchyma and cystic features, helping distinguish benign from premalignant or malignant processes. If imaging still leaves questions, endoscopic ultrasound with fine-needle aspiration or cyst fluid analysis can provide tissue or cyst fluid markers to guide management. Immediate surgery isn’t warranted based solely on an indeterminate CT when there’s no clear malignant feature, and observation alone risks missing a treatable lesion. No additional imaging would leave the indeterminate finding unresolved, so advising further imaging to characterize the lesion is the appropriate next step.
