A peritoneal abscess is a localized collection of pus within the abdominal cavity, often resulting from ruptured appendicitis, diverticulitis, or surgical complications. In abdominal ultrasound, it appears as a complex fluid collection with irregular walls, internal echoes, and often gas bubbles, differentiating it from simple fluid.
Diagnosing a peritoneal abscess with abdominal ultrasound is crucial for guiding drainage procedures and managing sepsis. Key features to identify include its echogenicity, presence of septations, and surrounding inflammatory changes, aiding medical professionals in accurate and timely intervention.
