title: Diagnosis of amoebic infection of the liver: report of 36 cases.
abstract: The classical clinical picture of amoebic infection of the liver consists of fever, right upper quadrant pain and hepatomegaly. In recent years, the widespread availability of ultrasound and serology made an early diagnosis possible, which could result in less prominent clinical pictures. Thirty six cases of liver amoebiasis diagnosed in Antwerp between 1985 and 1992, were reviewed. Three patients acquired their infection in Belgium. For the other patients, the average delay between arrival in Belgium and the first symptoms was 5.64 months. The classical triad of clinical signs (fever, right upper quadrant pain and hepatomegaly), was observed in only 13.9% of the patients, whereas it was much more frequent in earlier studies (68-75%). The right lobe was the most frequently affected (94%). The colour of the liquid, obtained by puncture, was brown in 61% of patients in whom it was reported. Amoebic cysts were found in the stools of only one patient. Amoebic serology was initially negative in only one patient, but became positive on second testing. Chest X-rays were abnormal in 34% of the patients. All patients who develop unexplained fever during the year after a stay in tropical countries should undergo an abdominal ultrasound examination and serological testing for Entamoeba histolytica.
