Abdominal pain resulting from cerebrospinal fluid pseudocyst and cholelithiasis

Patients treated with ventriculoperitoneal (VP) shunt procedures for hydrocephalus may have abdominal pain related to complications stemming from the shunt tubing itself or to other intra-abdominal disease. In patients with VP shunts, usually children, lack of absorption of cerebrospinal fluid (CSF) may produce a painful abdominal CSF pseudocyst. We have reported the rare occurrence of a CSF pseudocyst in an adult. The patient was also found to have cholelithiasis.
