A liver abscess is a pus-filled lesion within the liver, typically resulting from bacterial, parasitic, or fungal infections. In abdominal ultrasound, it appears as a hypoechoic or anechoic mass with irregular borders, often exhibiting internal debris or gas. Early detection via medical ultrasound is crucial for guiding drainage and antibiotic therapy to prevent complications.
Ultrasound is the primary imaging modality for diagnosing liver abscesses due to its non-invasive nature and real-time capabilities. Sonographic findings, including size, location, and internal characteristics, are essential for differentiating abscesses from other liver lesions and for monitoring treatment response, making it a key tool in abdominal medical imaging.
