Case Report - Abdominal CSF pseudocyst in a pateint with ventriculo-peritoneal shunt

Abdominal cerebrospinal fluid (CSF) pseudocyst is an uncommon complication of ventriculo-peritoneal shunts. We report a case of a large lesser sac CSF pseudocyst in a 63-year-old male operated for fibroblastic meningioma of the cerebello-pontine angle ten years earlier. During the initial surgery a ventriculo-peritoneal catheter was inserted for associated hydrocephalus. He presented with epigastric pain and swelling since 4 weeks. A CT scan of the abdomen revealed a large cystic mass in the lesser sac with thin enhancing walls. An exploratory laparotomy was performed and the cyst drained externally with revision of the shunt. The patient had a rapid and uneventful recovery. We report this uncommon occurrence with a brief review of the literature.
