Abstract:
:Hepatic actinomycosis is an uncommon entity that forms communicating abscesses and fistulae. A case is presented in which findings on ultrasound, CT, and percutaneous injection of the abscess all reflected the pathologic process. Biopsy by thin-needle aspiration under CT guidance afforded prompt, accurate diagnosis and effective therapy.
