Abstract
A 72-year-old female was admitted with the symptoms of malaise, loss of appetite, upper right quadrant pain, fever, and sweats, which had been present for last 7 days. CT-scan of the abdomen revealed a hypodense mass in the right liver lobe; histopathological examination of the biopsy specimen yielded a diagnosis of actinomycotic abscess. Treatment with intravenous ampicillin for 8 weeks followed by a course of oral doxicycline for 28 weeks resulted in the complete resolution of the abscess.
Highlights
Actinomycosis is an indolent, slowly progressive bacterial infection caused by a variety of Grampositive, non-spore-forming anaerobic germs included in the genus Actinomyces
Many Actinomyces species are opportunistic pathogens and are included in commensal flora that is found in the oropharynx, gastrointestinal tract, and female genital tract
We report a case of a patient with isolated hepatic actinomycosis cured with medical treatment alone
Summary
Actinomycosis is an indolent, slowly progressive bacterial infection caused by a variety of Grampositive, non-spore-forming anaerobic germs included in the genus Actinomyces. While cervicofacial infection is the most frequent manifestation of the disease, gastrointestinal involvement occurs in about 13% to 60% of the cases, in the oral cavity [1]. These bacteria can cause disseminated actinomycosis, a disease characterized by the formation of abscesses in the mouth, lungs or the gastrointestinal tract.
