英文摘要 | Pyogenic liver abscess of odontogenic origin in an immunocompetent patient is extremely rare. We report an immunocompetent 25-year-old male hepatitis B carrier with severe dental disease that led to the development of liver abscess. A periapical abscess in the upper left molar area was seen on his dental X-ray. Two sets of blood cultures grew Prevotella species, bacteria that are commonly found inside the oral cavity. Bacterial culture of the liver abscess drainage sample grew both Prevotella and Fusobacterium necrophorum. This led to our diagnosis of pyogenic liver abscess of dental origin, since we found no other source of infection in our patient except for his dental disease. After antibiotic therapy with drainage, abdominal sonography showed resolution of the abscess. The diseased teeth were also extracted. During 1 year of follow-up, there was no sign of abscess recurrence. A diagnosis of pyogenic liver abscess necessitates a complete evaluation to rule out possible biliary, colonic or other associated diseases. However, when a liver abscess is thought to be cryptogenic, we also recommend a careful dental examination to help identify the source of infection. |
