Which elements should be included in a CT description of a pancreatic lesion to characterize it?

Which elements should be included in a CT description of a pancreatic lesion to characterize it?

• A. Time of day
• B. Location (head/body/tail), size, attenuation, enhancement pattern, ductal involvement, and differential considerations; advise further imaging if indeterminate
• C. Patient age and gender
• D. Family history

Answer: (B)

The essential idea is to document imaging features that define what the pancreatic lesion is and how it could behave clinically. Start with exact location within the gland (head, body, or tail) because location influences likely diagnoses, symptoms, and surgical planning. Record the size, ideally the maximum dimension, since lesion size informs staging and resectability. Describe attenuation and how the lesion appears on different phases of contrast-enhanced CT, since this pattern helps separate solid from cystic processes and points toward specific pathologies (for example, hypoattenuating and less enhanced lesions favor adenocarcinoma, while hypervascular enhancement suggests neuroendocrine tumors). Note how the lesion interacts with the pancreatic ducts, including any dilation of the main duct or side branches, as ductal involvement guides differential and management. Provide a concise differential that integrates location, size, attenuation, enhancement, and ductal findings to steer further testing. If the lesion remains indeterminate, advise additional imaging or procedures such as MRI/MRCP or endoscopic ultrasound with possible tissue sampling to refine characterization and plan treatment.
