Hemoperitoneum at the splenorenal recess. An ultrasound image of the splenorenal recess (Koller’s pouch). A phased-array cardiac transducer was used with the abdominal settings. The left arrow indicates the diaphragm. The right arrow indicates the splenorenal recess with a hypoechoic collection between the spleen (left) and the left kidney (right). This is the image of free intraperitoneal fluid and is very suggestive for intraperitoneal hemorrhage when encountered in a trauma victim
