Intraperitoneal cerebrospinal fluid pseudocyst (CSF pseudocyst) is a rare but important complication in patients with ventriculoperitoneal shunts (VP shunts). It is often precipitated by inflammatory process or recent abdominal surgery and should be considered in VP-shunted patients presenting with abdominal complaints. This report presents a 74-year-old male with VP shunt insertion for 4 years without complication. However, the patient developed CSF pseudocyst soon after recent laparotomy.
