A Case of Large Hepatic Cyst Infected with Salmonella paratyphi A / 감염과화학요법

ABSTRACT

Salmonellae cause a number of characteristic clinical infections in humans, including gastroenteritis, enteric fever, bacteremia, focal metastatic infection and an asymptomatic chronic carrier state. We report a case of large hepatic cyst infected with Salmonella paratyphi A. A 47-year-old woman was admitted, because of abdominal complains (fullness and pain) and fever. On physical examination, a mass was palpated on right upper quadrant of the abdomen. The computerized tomography of the abdomen showed a large hepatic cyst, but not cystic infection. Aspiration and percutaneous drainage of the hepatic cyst were perfomed for the therapeutic decompression under fluoroscopic guidance. Cultures of the cyst fluid revealed growth of Salmonella paratyphi A. Radiologic contrast media after draining of the cyst fluid revealed no communication between the cyst and bile ducts. Infected hepatic cyst appeared to result from hematogenic seeding. One month later, the patient improved and was discharged without any complication.
