Hepatic abscess and hydatid liver cyst: European infectious disease point of view

This manuscript is based on a recent study by Pillay <i>et al</i> that was published in recently. Liver abscesses can be caused by rare potentially life-threatening infections of either bacterial or parasitic origin. The incidence rate in Europe is lower than in developing countries, but it is a major complication with high morbidity, particularly in immunocompromised patients. They are most frequently caused by <i>Enterobacterales</i> infections, but hypervirulent <i>Klebsiella</i> strains are an emerging problem in Western countries. Amoebiasis has been a public health problem in Europe, primarily imported from other endemic foci. At the same time, this infection is becoming an emerging disease, as the number of infected patients who have not traveled to endemic areas is rising. Treatment options for hydatid liver cyst include chemotherapy, open or laparoscopic surgery, percutaneous treatment (percutaneous aspiration, re-aspiration and injection and its modification) and ''wait and watch'' strategy. Most hydatid liver cyst patients in Pillay <i>et al</i>'s study received surgical treatment, but several studies have confirmed the safety and efficacy of percutaneous aspiration, re-aspiration and injection.
