[Rectocolic lymph node appearance in adults (author's transl)]

A Weissman, H J Barge, M Clot

    Journal De Radiologie
    |August 1, 1981
    PubMed
    Summary

    The characteristic rectocolic lymph follicle appearance, seen in 3.5% of barium enemas, is usually normal. Rare cases may indicate immune deficiency, requiring further investigation.

    Area of Science:

    • Gastroenterology
    • Radiology
    • Immunology

    Background:

    • Double contrast barium enemas are utilized for radiological examination of the colon.
    • The study investigates a specific radiological finding termed 'lymph follicle appearance' in the rectocolic region.

    Observation:

    • A characteristic 'lymph follicle appearance' was noted in 3.5% of 480 patients.
    • This appearance presents as small (1-3 mm) lacunae with indistinct borders across colon segments.
    • The frequency is linked to the double contrast technique and barium adherence.

    Findings:

    • In most instances, the 'lymph follicle appearance' represents a normal variation.
    • Rare presentations may suggest partial immunity deficiency.
    • Differential diagnoses include early-stage colon wall edema and polyposis disorders.

    Implications:

    • The finding is typically benign but warrants consideration for immune deficiency in rare cases.
    • Coloscopy with biopsy is recommended for uncertain diagnoses.
    • Highlights the importance of radiological interpretation in identifying subtle colonic variations.
