Answer: 

Typically, the blood within the peritoneal cavity will appear anechoic. However, it may also appear hypoechoic or hyperechoic in some instances. So, examine carefully and do not miss evidence of fluid in the peritoneal cavity. Always correlate clinically. When in doubt, order a CT scan if the patient is hemodynamically stable. If that option is not available, then perform serial ultrasound scans and monitor patient’s vitals closely at short intervals.
