Unusual Complication of Abdominal Pseudocyst Following Cystoperitoneal Shunt in Posterior Cranial Fossa Arrachnoid Cyst

Abdominal pseudocyst is a rare complication reported of VP shunt surgery. Here, we report a 10-monthsoldboy with abdominal distension following cystoperitoneal (CP) shunt procedure for the fossa posteriorarrachnoid cyst. The diagnosis was based on the clinical symptoms and abdominal USG. Infection andallergic reaction was considered as the underlying cause. The CP shunt was removed to atrioventricularshunt and it resulted in a good response. Abdominal pseudocyst should be considered whenever there isabdominal distension following VP/CP shunt.
