    Abstract:
    BACKGROUND Amebiasis is a parasitic infection caused by the protozoan Entamoeba histolytica. Amebic brain abscesses are a rare form of invasive amebiasis frequently lethal due to the difficulty of its diagnosis and inadequate treatment. Cerebral amebiasis poses a therapeutic challenge as evidenced by the scarcity of papers reporting complete recovering after treatment. CASE REPORT We report the case of a 39-year-old Spanish man, with a history of alcohol and drug abuse. He had never traveled outside of Europe, no reported oral-anal sexual contact, and no history of immunosuppressant medication. He was admitted to the Emergency department with temperature of 38°C, abdominal pain, and diarrhea. An abdominal CT scan showed multiples abscesses in the liver. Therefore, empirical meropenem treatment was started on suspicion of pyogenic liver abscesses due to lack of epidemiological risk factors for parasitic infection. In the liver aspirate samples, E. histolytica trophozoites were directly visualized and a real-time PCR was also positive for it. After amebiasis diagnosis, intravenous (IV) metronidazole therapy was initiated. During his admission, the patient developed pulmonary, cutaneous and cerebral involvement amebiasis. The management of amebic brain abscesses includes surgical drainage and antiparasitic treatment, in our case IV metronidazole was maintained for 10 weeks. No surgical treatment was performed and even so, the patient evolved favorably. CONCLUSIONS Amebic brain abscesses have a high mortality rate if inadequate treatment. A timely diagnosis and suitable treat can reduce its mortality, so the diagnosis of amebic infection should not be precluded in non-endemic countries.
