What is the treatment for echinococcus infection presenting with liver abscess?

• A. Oral antivirals
• B. Resection of part of the liver and albendazole
• C. Observation only
• D. Intravenous antifungals

Answer: (B)

The treatment for echinococcus infection that presents with a liver abscess typically involves a combination of surgical and medical management. Resection of part of the liver aims to remove the hydatid cysts causing the abscess, which are a result of an Echinococcus spp. infection. Surgical intervention is necessary because simply treating the cysts with medication may not address the immediate complications, such as abscess formation, and can carry a risk of rupture or secondary infection.

Albendazole is an important adjunct therapy in the treatment because it is effective against echinococcal infections by killing the parasite and preventing further growth. This dual approach—surgical resection combined with albendazole—helps reduce the risk of recurrence and complications associated with the disease.

The other treatment options listed would not appropriately address the situation. Oral antivirals are not indicated for echinococcus infections as they target viral infections, while intravenous antifungals are inappropriate since echinococcus is a parasitic infection, not a fungal one. Observation alone would not effectively treat a liver abscess caused by this parasite, as it could lead to complications if the condition worsens without intervention.
