    Pelvic computed tomography (CT) and contrast enema effectively diagnose diverticulitis extent. CT imaging reveals extracolonic disease and bladder changes, guiding treatment decisions.

    Area of Science:

    • Radiology
    • Gastroenterology
    • Surgical Oncology

    Background:

    • Diverticulitis diagnosis and staging are crucial for effective patient management.
    • Traditional methods like contrast enema and sigmoidoscopy have limitations in assessing extracolonic disease.

    Observation:

    • Computed tomography (CT) of the pelvis was utilized to study six cases of diverticulitis.
    • CT effectively visualized intramural and extracolonic components of diverticulitis, including abscess formation.
    • Changes in the urinary bladder contour were observed in cases of extracolonic abscess.

    Findings:

    • CT identified inflammatory extracolonic masses as low or mixed-attenuation lesions, often with gas pockets.
    • Bladder wall thickening, edema, and contour asymmetry indicated pericolonic or extracolonic extension.

    Related Experiment Videos

  • CT directly images pelvic inflammatory masses and associated anatomical changes, complementing contrast enema findings.

    • Implications:

    • Integrated CT and contrast enema studies accurately define diverticulitis extent.
    • Accurate staging significantly impacts the choice between medical and surgical management strategies.
    • CT provides a comprehensive evaluation of diverticulitis, including secondary pelvic changes beyond the bowel wall.
