반복적인 치주질환을 가진 환자에서 발생한 Fusobacterium nucleatum 에 의한 화농성 간농양 = A Case of Liver Abscess Caused by Fusobacterium nucleatum in a Patient with Recurrent Periodontal Diseases

다국어 초록 (Multilingual Abstract)

Fusobacteria are anaerobic gram-negative, non-spore forming bacilli found in normal flora of the oral cavity, urogenital tract, and gastrointestinal tract. Fusobacterium nucleatum has been seldom reported as a cause of liver abscess, particularly in immunocompetent hosts. A 55-year-old man with frequent periodontal disease visited our hospital with intermittent fever and headache for 2 months. Abdominal CT scan revealed an 8.2×6 cm mass in the right hepatic lobe with central low density. Abscess culture revealed F. nucleatum as the causative organism. Percutaneous abscess drainage and intravenous administration of antibiotics for 4 weeks improved symptoms and decreased the abscess size. We report a rare case of liver abscess due to F. nucleatum in an immunocompetent man with periodontal disease. (Korean J Gastroenterol 2011;57:42-46)
