Abdominal hydropoint sign in pneumoperitoneum diagnosis

Abstract Early and accurate detection of pneumoperitoneum is crucial for effective patient management. We present the case of a 49‐year‐old patient with no pertinent medical history who fell from a height of 5 m, resulting in pelvic and abdominal trauma requiring surgical intervention. Due to fever, ultrasound assessment revealed an anechoic image consistent with free fluid, along with reverberating artifacts originating from the peritoneal line, suggesting pneumoperitoneum. In this case, we describe an ultrasonographic dynamic sign termed the “abdominal hydropoint sign,” observed during point‐of‐care ultrasound, which can aid in diagnosing pneumoperitoneum within the clinical context.
