HEPATIC ACTINOMYCOSIS: A CASE REPORT.

Primary hepatic actinomycosis is one of the chronic abscess-forming infections of the liver. Its diagnosis is frequently delayed due to its indolent course and nonspecific clinical and radiological manifestations. This article reports a 23 years old man presented with a 2-week history of right upper quadrant pain with fever. Ultrasonography and abdominal CT scan sowed a voluminous multilocular lesion between IV, V, VI liver segments. The postoperative pathological examination found multifocal actinomycetes in the hepatic parenchyma. Large doses of sodium penicillin were administered postoperatively as anti-infective therapy. This case suggests that primary hepatic actinomycosis should be considered as one of the extensive causes for liver abscess.
