CASE REPORT: The authors present a case of a patient

with an abdominal CSF pseudocyst that resulted from an

allergic reaction to silicone. The patient underwent

repair surgery of the meningomyelocele associated with

the Chiari II malformation, and the V-P shunt was

instituted at 6 months of age. A formation of the

abdominal CSF pseudocyst and the consequent shunt

malfunction were observed 40 days after the V-P shunt.

An increase in the number of the peripheral

eosinophils and serum immunoglobulin E (IgE), and an

infiltration of eosinophils in the specimen harvested

from the pseudocyst wall suggested an allergic

reaction as the cause of the pseudocyst. A sixth

operation to revise the V-P shunt was performed using

the shunt system made of " extracted silicone " , which

was produced extracting the allergic substances.

OUTCOME: The serum IgE was normalized after surgery

and the abdominal CSF pseudocyst has not recurred for

22 months.
