Abstract
There are no reports on a liver abscess caused by Lactobacillus in the literature. Therefore we report a rare case of this phenomenon. A 68-year-old woman who had subtotal gastrectomy and cholecystectomy four months before was admitted to our hospital because of high fever and right chest pain. A chest roentgenogram showed right pleural effusion. Abdominal ultrasonography revealed a hypoechoic mass in the posterior segment of the liver. A computed tomography revealed a heterogeneous low density mass in the liver. The diagnosis was liver abscess. We treated the patient with antibiotics, but the symptoms became worse and worse. On the 6th drainage contents were milky pus. The causative organism was identified as Lactobacillus catenaforme.
