Two years before admission he had worked as a sailor in South America, and one year ago he had been in Gran Canaria for a vacation. No serious illness occurred during these stays abroad. During the hospitalization the patient reported nausea and experienced upper right abdominal pain. Ultrasonography, computed tomography and serological tests revealed an amebic liver abscess. After administration of metronidazole the fever and symptoms subsided.
