=====Hepatic cerebrospinal fluid (CSF) pseudocyst===== 
Is a rare but important complication in patients with a [[ventriculoperitoneal shunt]] insertion. 

Once the diagnosis is verified and if the [[cerebrospinal fluid]] CSF is sterile, just simply remove the [[peritoneal catheter]] and reposition a new one in the abdomen. 

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
