Flexural pseudolesions of the duodenum

M Burrell, R Toffler

    Radiology
    |August 1, 1976
    PubMed
    Summary

    Barium collections in the duodenum can mimic ulcers or masses. These simulated defects, often at the duodenal junction, are usually benign and differ from true lesions.

    Area of Science:

    • Gastrointestinal Radiology
    • Diagnostic Imaging

    Background:

    • Barium studies frequently reveal duodenal defects.
    • These findings can be mistaken for serious pathology like ulcers or masses.

    Purpose of the Study:

    • To describe a common barium artifact in the duodenum.
    • To differentiate this artifact from true gastrointestinal lesions.

    Main Methods:

    • Review of barium studies showing defects at the duodenal bulb/second portion junction.
    • Correlation with endoscopic findings and imaging characteristics.

    Main Results:

    • A collection of barium can simulate an ulcer or mass.
    • Factors include flexion, sphincter function, and extrinsic impressions.
    • Endoscopy often reveals normal findings in these cases.

    Conclusions:

    • The described barium collection is a benign finding.
    • Characteristic location and variable appearance distinguish it from true lesions.
