Abstract:
Amebic liver abscess is an emergent disease in Spain due to immigration and travel to endemic countries. Although mainly pharmacological, treatment can sometimes require drainage, especially when there is a high risk of rupture due to location or size. We report a case of amebic liver abscess that, due to its large size and lack of response to metronidazole therapy, required percutaneous drainage. This technique, with ultrasound-guided percutaneous aspiration, would be indicated in lesions with a diameter of > 5 cm, abscesses of the left lobe, and those unresponsive to medical treatment.
Insights
Amebic liver abscesses in Spain, often linked to travel, may need drainage if large or unresponsive to medication. Ultrasound-guided percutaneous drainage is recommended for abscesses over 5 cm, in the left lobe, or those not improving with metronidazole.
Area of Science:
- Hepatology
- Infectious Diseases
- Radiology
Background:
- Amebic liver abscess (ALA) is an emerging concern in Spain, influenced by immigration and international travel.
- While medical therapy is primary, surgical or interventional drainage may be necessary in complex cases.
Observation:
- A case of a large amebic liver abscess unresponsive to metronidazole therapy is presented.
- The abscess required intervention due to its size and location, posing a risk of rupture.
Findings:
- Ultrasound-guided percutaneous drainage was successfully employed for the amebic liver abscess.
- Key indications for this intervention include abscesses > 5 cm, left lobe involvement, and lack of response to medical treatment.
Implications:
- Percutaneous drainage offers a minimally invasive option for managing complicated amebic liver abscesses.
- This approach can improve patient outcomes when medical management alone is insufficient, particularly in high-risk cases.
