Abbreviations
- Inflammatory bowel disease (IBD)
- Crohn disease (CD)
Definitions
- Perienteric inflammatory masses
- Phlegmon: Vascularized, inflammatory mass that is still perfused and cannot be drained
- Abscess: Localized, suppurative, avascular collection of pus amenable to drainage and encompassed by inflamed tissue
- CEUS fistulography: Technique in which microbubble contrast agent injected directly into cavity or sinus tract
- Inflammatory masses within bowel
- Inflammatory polyp: Nonneoplastic intraluminal vascular mass composed of nonepithelialized granulation tissue admixed with inflammatory cells
- Intramural abscess: Avascular collection of pus located within bowel wall, shown on grayscale US as asymmetric, hypoechoic mural mass
- Perienteric inflammatory masses
Contributions of US/CEUS
- CEUS can differentiate nature of inflammatory mass as abscess or phlegmon
- CEUS offers several advantages to clinical management, all of which lend further support for inclusion of this imaging modality into clinical practice
- CEUS is
- Noninvasive
- Easily repeatable
- Free of ionizing radiation
- Well tolerated
- Flexibility of US/CEUS overall enhanced for this application by addition of
- Endovaginal scans in women for accurate assessment of pouch of Douglas and deep loops of bowel
- Transperineal scans in both men and women for confirmation of perianal abscess and fistula
- CEUS fistulography to potentially replace standard fistulography without requirement of ionizing radiation
