There is a central area of decreased echogenicity, possibly representing fluid within the appendix, and there is a somewhat eccentrically placed fluid collection near the appendiceal tip which may represent a very early perforation. There is inflammation of peri-appendiceal fat and a marked increase in blood flow seen on Doppler imaging. The liver, spleen, kidneys, gallbladder, and pancreas are normal. Thickening of appendix with surrounding inflammation consistent with appendicitis.
