Ascending colon compression by psoas muscle hypertrophy.

K L Cover, B S Slasky, P M Bonadio

    The American Journal of Gastroenterology
    |February 1, 1983
    PubMed
    Summary

    Psoas muscle enlargement can cause extrinsic colon compression in athletes, mimicking pathology on barium enema. Ultrasound can distinguish this muscular variant from serious conditions affecting the colon and ureters.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Musculoskeletal Imaging

    Background:

    • Barium enema is a common diagnostic tool for evaluating the colon.
    • Extrinsic compression can present diagnostic challenges, potentially mimicking intrinsic colonic disease.

    Observation:

    • A professional athlete presented with extrinsic compression of the ascending colon on barium enema.
    • Ultrasound examination revealed enlarged psoas muscles as the cause.

    Findings:

    • Psoas muscle hypertrophy can lead to apparent extrinsic compression of the ascending colon.
    • This finding is particularly relevant in muscular individuals.

    Implications:

    • Consider psoas muscle hypertrophy in the differential diagnosis of ascending colon extrinsic compression in athletes.
