BackgroundVentriculoperitoneal (VP) shunts are among the most frequently performed operations in the management of hydrocephalus. Hepatic cerebrospinal fluid (CSF) pseudocyst is a rare but important complication in patients with a VP shunt insertion. In addition to presenting our own case, we performed a PubMed search to comprehensively illustrate the predisposing factors, clinical picture, diagnostic methods, and surgical treatment. This article represents an update for this condition.Case DescriptionA 40-year-old male was admitted to a hospital complaining of fever, abdominal distention, and pain. He had undergone a VP shunt for communicating hydrocephalus caused by a head trauma one year earlier. Laboratory studies showed liver enzymes alterations, and imaging studies demonstrated a well-defined intraaxially hepatic cyst with the shunt catheter placed inside. Staphylococcus epidermis was cultured via CSF. After removing the VP shunt and an adequate antibiotic treatment, the complication of hepatic CSF pseudocyst was resolved.ConclusionHepatic CSF pseudocyst is a rare complication of a VP shunt. Once the diagnosis is verified and if the CSF is sterile, just simply remove the peritoneal catheter and reposition a new one in the abdomen. We believe that it is not necessary to remove or aspirate the hepatic intraaxial pseudocyst, because of the risk of bleeding. In case of CSF infection, the VP shunt can be removed and/or an external derivation can be made, and after treatment with antibiotics, a new VP shunt is placed in the opposite side of the peritoneum.
