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.
