[Ultrasonics in the diagnosis of liver abscess].

Echography is a quick and simple method for the diagnosis and monitoring of liver abscesses. It provides accurate information on the nature of the lesion and permits echo-guided percutaneous aspiration of the abscess, a manoeuvre presenting almost no risk of complications. The latter technique has proved a valid alternative to surgery since it permits the introduction of the drug employed into the abscess cavity and the consequent healing of bacterial and amoebic lesions in a very few days. Some personal results are presented.
