Patients with a ventriculoperitoneal shunt placed for therapeutic relief of increased intracranial pressure are known to have abdominal complications including cerebrospinal ascites. More common complications are mechanical malfunction due to tip occlusion by fibroid encasement or omental clogging. Other complications include infection, cerebrospinal pseudocysts and loculations, intestinal obstruction secondary to adhesions, perforation of viscera, and migration of shunt. The shuntogram in an 18-year-old woman with a myelomen-ingocele, Chiari II malformation showed a large nonloculated fluid collection in the peritoneum. Analysis of the ascitic fluid verified cerebrospinal fluid.
