A Case of Liver Abscess Probably Caused by Acute Appendicitis

A 22-years old woman admitted to our hospital with a high-grade fever reported abdominal pain. She was diagnosed with acute enteritis in an other hospital a week before. She also demonstrated McBurney's sign and rebound soreness in the abdomen. Emergency surgery was undertaken based on a dignosis of peritonitis due to acute appendicitis. Puruloid ascites was seen near the ileocecum. Appendectomy and drainage of the peritoneal cavity were conducted. Appetite loss, general malaise, and a slight fever continued postoperatively. Abdominal computed tomography 14 days postoperatively showed a low-density area at the liver S6 80 mm in diameter. Suspecting a liver abscess, we conducted US-guided percutaneus abscess drainage. Antibiotics were administered both systemically and directly into the abscess cavity. After drainage for 21 days, the abscess cavity disappeared and the catheter was removed 29 days after drainage.
