    Ultrasound reveals diverse chronic pancreatitis signs, including varied echogenicity and gland enlargement. Many patients showed normal sonograms, challenging previous assumptions about diagnostic accuracy for this condition.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Medical Imaging

    Background:

    • Chronic pancreatitis diagnosis relies on various clinical and imaging modalities.
    • Previous ultrasound literature described a limited range of findings for chronic pancreatitis.

    Purpose of the Study:

    • To determine the frequency of specific sonographic findings in chronic pancreatitis.
    • To identify less commonly described ultrasound presentations of chronic pancreatitis.

    Main Methods:

    • Retrospective analysis of 84 ultrasound examinations from 77 patients diagnosed with chronic pancreatitis.
    • Evaluation of sonographic findings including echogenicity, gland size, calcifications, and pseudocysts.

    Main Results:

    • Common findings: increased echogenicity (53%), gland enlargement (41%), focal dense echoes (40%), pseudocysts (21%).

  • Uncommon presentations: pancreatic or bile duct enlargement, pseudocysts with normal glands.
  • 13% of patients had normal sonograms; no correlation between echoes and calcification or pancreatic insufficiency.

    • Conclusions:

    • Sonographic findings in chronic pancreatitis are more varied than previously reported.
    • Ultrasound can reveal diverse presentations, including subtle signs in patients without obvious gland changes.
