A06.4
Amebic liver abscess
Clinical Classification Guidelines
Inclusion Terms
- Hepatic amebiasis
Medical Intelligence & Overview
Amebic liver abscess, also known as hepatic amebiasis, is a localized collection of pus in the liver caused by the parasitic infection Entamoeba histolytica. This condition typically develops when the parasite invades the liver through the portal circulation after infection in the intestines. It is most common in regions with inadequate sanitation and is considered a serious complication of amebiasis, which primarily affects the gastrointestinal tract. Proper diagnosis and treatment are essential to prevent complications and promote recovery.
Causes & Symptoms
Clinical Causes: Infection with the parasite Entamoeba histolytica. Contaminated food or water sources that contain the cysts of the parasite. Poor sanitation practices leading to fecal-oral transmission.
Key Symptoms: Fever and chills. Right upper quadrant abdominal pain or tenderness. Fatigue and malaise. Loss of appetite. Weight loss. Possible hepatomegaly (enlarged liver). In some cases, jaundice (yellowing of the skin and eyes).
Diagnostic & Treatment
Diagnosis Path: Diagnosis of amebic liver abscess involves a combination of clinical evaluation, imaging studies, and laboratory tests. Imaging techniques such as ultrasound or computed tomography (CT) scans can confirm the presence of a liver abscess. Laboratory tests, including serology for E. histolytica antibodies and stool analysis, help identify the parasitic infection. In some cases, aspiration of the abscess may be performed to obtain a sample for further testing. Clinicians may also evaluate liver function tests and blood counts to assess the severity of the infection and rule out other causes of liver lesions.
Treatment Protocols: Treatment typically includes antimicrobial medications effective against Entamoeba histolytica, such as nitroimidazoles (e.g., metronidazole) followed by a lumenal agent (e.g., paromomycin) to eradicate intestinal cysts. In severe cases or if complications arise, surgical intervention or drainage of the abscess may be required. Supportive care, including hydration and pain management, is also important. Rapid treatment initiation improves outcomes and reduces the risk of rupture or other complications.
