[Pyogenic hepatic abscesses: role of ultrasonography in their diagnosis and treatment].

Abstract

We present 26 cases of pyogenic hepatic abscess diagnosed by echography, 14 of which were treated by percutaneous drainage guided by ultrasound. An analysis is made of the clinical and radiological findings, as well as the differential diagnosis of focal hepatic lesions. Due to the lack of clinical specificity in many patients, we recommend fine needle biopsy directed by ultrasound to confirm the suspicion of pyogenic hepatic abscess and isolation of noncausative microorganisms. We think that the treatment of choice in these patients is percutaneous drainage guided by echography.
