Ultrasonography in the diagnosis and management of 52 patients with amebic liver abscess in Cairo.
Clinical characteristics of 52 patients with amebic liver abscess are reported. Forty-two percent had an acute illness, usually with high fever, vomiting, sweating, pain in the abdominal right upper quadrant, and leukocytosis. The other 58% had a more chronic illness, usually with a dull ache in the right upper abdomen, weight loss, fatigue, moderate or low-grade pyrexia, and anemia. Hepatomegaly and hepatic tenderness were present in all patients; fever occurred in 75%. The diagnosis was strongly suggested by amebic antibodies in high titer and hepatic abscesses demonstrated by sonography. Mean abscess diameter was 9.2 cm; 37% were larger than 10 cm. Most abscesses were solitary (81%), in the right lobe (73%), rounded or oval (78%), cystic (57%), and had a well-defined wall (53%). However, 43% were initially solid or heterogeneous. The latter lesions always developed a cystic pattern when ultrasonography was repeated. The diagnosis was confirmed by a good clinical response to metronidazole in 50 patients. Complications included right-sided pleural effusions or empyema (13%), ascites (13%), and jaundice (13%). Drainage of large abscesses was performed in four patients. All 52 patients survived and were cured.
