AbstractLiver abscess is a rare complication following the ventriculoperitoneal (V-P) shunt operation. There has been only one case reported in the literature. We present a case of liver abscess developed about 3 months after V-P shunt operation. A 31-year-old female was admitted to our hospital in comatose condition due to second bleeding from an aneurysm of the right internal carotid artery on January 1, 1984. Obliteration of the aneurysm was performed on the following day. She received V-P shunt operation for the marked hydrocephalus on February 4, but she developed low spinal fluid pressure syndrome. She was able to walk by herself after the replacement of shunt valve on March 4. In the middle of April, she suffered from abdominal pain with a pyrexia for about 5 days. On May 13, a new peritoneal tube was placed in another part of the peritoneal cavity because of the recurrence of hydrocephalus. On the following day, she developed severe abdominal and back pains with a high fever. Abdominal CT scans and ultrasonogram were performed on May 22, showing a well-defined, cystic mass lesion in the liver and the peritoneal tube lying just beneath the mass lesion. Approximately 100 ml of white creamy pus was aspirated from the cystic mass by ultrasound-guided percutaneous puncture, and a 8.3 French pigtail nephrostomy catheter was left in place for 9 days until purulent drainage stopped. Microbiologic examination demonstrated staphylococcus epidermidis in the cerebrospinal fluid (CSF) from the shunt tube but was negative in the abscess fluid. The ventricular fluid was drained externally with the V-P shunt tube for a while, but the new ventricular drainage was instituted because of continuous positive cultures in the CSF from the shunt tube. Thereafter, the cultures of the CSF became negative and ventriculoatrial (V-A) shunt operation was performed on July 2. Postoperative course was uneventful. It is considered that the formation of the liver abscess seems to be caused by the focal injury to the liver surface by the insidiously infected peritoneal tube with St. epidermidis, and by the decrease in systemic resistance to infection. Percutaneous aspiration and drainage under the guidance of abdominal computed tomography or ultrasonography are very useful and efficient for the diagnosis and the treatment of liver abscess. When patients show signs of infection to the V-P shunt, we should remove the shunting system and place a new external ventricular drainage, and institute a V-A shunt after confirming negative cultures of the CSF.
