Purpose

The purpose of the study was to evaluate the usefulness of contrast-enhanced ultrasound (CEUS) to diagnose and/or differentiate between intra-abdominal phlegmon and abscess.

Methods and Materials

We retrospectively reviewed the reports of all CEUS for gastrointestinal application in our Hospital performed between June 2006 and May 2012 to identify all patients with the terms “inflammatory mass”, “phlegmon” or “abscess”. US examinations were performed by using a US unit (Aplio 80; Toshiba, Tokyo, Japan) by three radiologists with wide experience in US of intestinal bowel diseases as well as in CEUS. CEUS: Patients were examined with a 3-4 MHz convex probe in the wideband contrast harmonic mode (pulse inversion Toshiba Aplio) at...

Results

We performed 871 contrast-enhanced ultrasound (CEUS) for gastrointestinal application between June 2006 and May 2012. Of these, a group of 80 patients were included because terms as “inflammatory mass”, “phlegmon” or “abscess” were on the report. Nine examinations were excluded because of lack of confirmation or inadequate follow-up. Our final cohort consisted of 71 inflammatory masses in 50 patients, 22 women and 28 men with an average age of years 41 ± SD15 (range years: 18-77). Thirty-three patients had a confirmed diagnosis of Crohn´s disease,...

Conclusion

CEUS is an accurate method for differentiating between intra-abdominal phlegmon and abscess in gastrointestinal conditions, especially in Crohn’s Disease. Its use may help to better define the size of the collections and avoid other techniques that use ionizing radiation.
