Amebic liver abscess: sonographic diagnosis and management
Abstract:
Over a period of 3 years, 68 intrahepatic abscesses in 48 patients were detected by ultrasonography at our institution in New Delhi, India. Our experiences with the sonography and management of this entity are presented. Multiple abscesses were present in 14 patients; the rest had a single abscess. The most common location was the right lobe of the liver. The sonographic morphology of the abscess was analyzed in terms of the echo pattern of the wall and contents of the abscess. These were later correlated with the duration of illness. An attempt was made to assess healing and thereby the age of the abscess. Follow-up ultrasound scans indicated that the change in sonographic appearance lags behind clinical improvement by a considerable period of time.
Insights
Ultrasonography detected 68 intrahepatic abscesses in 48 patients over 3 years. Sonographic appearance changes lag behind clinical improvement, aiding in abscess age assessment.
Area of Science:
- Hepatology
- Radiology
- Medical Imaging
Background:
- Intrahepatic abscesses are significant clinical entities.
- Accurate diagnosis and management are crucial for patient outcomes.
- Ultrasonography is a primary imaging modality for liver abscesses.
Purpose of the Study:
- To present institutional experience with intrahepatic abscesses.
- To correlate sonographic findings with clinical data.
- To assess the utility of ultrasonography in evaluating abscess age and healing.
Main Methods:
- Retrospective analysis of 68 intrahepatic abscesses in 48 patients.
- Ultrasonography for detection and characterization.
- Analysis of abscess morphology (wall and content echo patterns).
- Correlation of sonographic findings with duration of illness and clinical improvement.
Main Results:
- 68 intrahepatic abscesses in 48 patients over 3 years.
- Most common location: right lobe of the liver.
- Multiple abscesses in 14 patients.
- Sonographic morphology correlated with illness duration.
- Ultrasound appearance changes lagged behind clinical improvement.
Conclusions:
- Ultrasonography is effective for diagnosing and characterizing intrahepatic abscesses.
- Sonographic features can provide insights into abscess age and healing.
- A temporal discrepancy exists between sonographic changes and clinical recovery.
