The peritoneal stripe normally is seen as a thin echogenic line on sonography, at the interface between the anterior abdominal wall and the underlying peritoneal fluid or solid organs (Fig. 1). In patients with pneumoperitoneum, high amplitude linear echoes are produced by scattering of the ultrasound waves at the soft tissue–gas interface, creating the enhanced peritoneal stripe sign (EPSS) (Fig. 2) [1‐3]. Larger amount of intraperitoneal gas produce multiple reverberation artifacts, which appears as horizontal stripes, echogenic lines with comet tail artifacts, or ring-down artifacts (Video 1) [3].
