Appendectomy induced hepatic cerebrospinal fluid pseudocyst in a shunted patient

Background: Abdominal intraperitoneal cerebrospinal fluid pseudocyst is a rare complication in patients with ventriculoperitoneal shunt insertion. Various predisposing factors such as infection, obstruction, dislodgement, and iatrogenic causes have been discussed. However, the pathophysiology of the condition remains unknown. Case Report: The case of a shunted patient who complained of fever and low abdominal pain 1 week after appendectomy is presented. The distal tube of the ventriculoperitoneal shunt migrated to the right upper quadrant, and a hepatic cerebrospinal fluid cyst was discovered via CT scan. After liver drainage, adequate antibiotic treatment, and externalization of the ventriculoperitoneal shunt, the hepatic cyst was resolved. There was no recurrence observed upon follow-up. Conclusion: Although abdominal intraperitoneal cerebrospinal fluid pseudocyst seldom is encountered clinically, proper management of a diagnosed cyst can provide complete amelioration.
