Sonography of appendiceal intussusception.

D D Maglinte, A C Fleischer, G T Chua

    Gastrointestinal Radiology
    |January 1, 1987
    PubMed
    Summary

    Appendiceal intussusception can be diagnosed before surgery using ultrasound. The characteristic "coiled spring sign" seen on sonography aids in identifying this condition.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging

    Background:

    • Appendiceal intussusception is a rare condition where the appendix telescopes into itself.
    • Preoperative diagnosis can be challenging, often requiring surgical exploration.

    Observation:

    • A case report detailing the preoperative sonographic diagnosis of appendiceal intussusception.
    • Sonography revealed a characteristic pattern of concentric hypoechoic and hyperechoic rings.

    Findings:

    • The sonographic finding of multiple concentric rings was confirmed intraoperatively as appendiceal intussusception.
    • The 'coiled spring sign' on ultrasound is a key indicator in the right lower quadrant.

    Implications:

    • Sonography can accurately diagnose appendiceal intussusception, potentially avoiding unnecessary laparotomies.
    • Recognizing the 'coiled spring sign' improves diagnostic accuracy for this uncommon condition.
