    Summary

    Radiologists should be aware of pseudoaneurysms, a rare complication of pancreatitis. Early detection on contrast-enhanced CT scans is crucial for reducing serious patient morbidity and mortality.

    Area of Science:

    • Radiology
    • Vascular Imaging
    • Gastroenterology

    Background:

    • Pancreatitis commonly leads to complications like pseudocysts and abscesses, which are familiar to radiologists.
    • The formation of pseudoaneurysms as a secondary complication of pancreatitis is less frequently emphasized in radiologic literature.

    Observation:

    • This study describes three patients with pancreatitis where pseudoaneurysms were identified.
    • These pseudoaneurysms were diagnosed using contrast material-enhanced abdominal computed tomography (CT) scans.
    • The scans were initially performed to evaluate the patients' pancreatitis.

    Findings:

    • Contrast-enhanced CT scans effectively demonstrated angiographically proven pseudoaneurysms in patients with pancreatitis.
    • A key finding is the characteristic appearance of a homogeneously enhancing structure.

  • This structure, found within or adjacent to a pancreatic pseudocyst or near a vascular structure, is highly suggestive of a pseudoaneurysm.

    • Implications:

    • Early and accurate detection of pseudoaneurysms associated with pancreatitis is vital.
    • Recognizing this complication can significantly reduce the high morbidity and mortality rates linked to pseudoaneurysms.
    • Radiologists should maintain a high index of suspicion for pseudoaneurysms in relevant CT findings during pancreatitis evaluations.
