Ultrasonographic images in the sagittal orientation of the umbilical region (A) and left lumbar (B and C) showing free abdominal air (arrows) that led to increased echogenicity and thickening of the peritoneal stripe with reverberation artifacts. Free abdominal air was present along the ventral peritoneum adjacent to the spleen and small intestine. Intraluminal air was also observed in the intestinal lumen (arrowhead) and associated with "dirty" acoustic shadowing.

Ultrasonographic  images  in  sagittal  orientation  in  the  left  lumbar  (A)  and  umbilical  region  (B,  C)  show  extraluminal air inducing linear enhancement and thickening of the peritoneal stripe sign (EPSS) associated with either dirty shadowing or reverberation artifacts (arrows). As injected air was added in increments (A: 0.1 ml, B: 0.2 ml, C: 0.4 ml), EPSS size was relatively increased. These results indicate that an increase in the EPSS size reflects an increase in the total extraluminal air within the abdominal cavity.
