[Manifestation of Chiari II symptoms following peritoneal shunt tube extension].
A 5-year-old boy with hydrocephalus and a lumbar myelomeningocele underwent extension of peritoneal tube of ventriculoperitoneal (VP) shunt system. Prior to the operation he had been able to walk independently with the use of braces, to speak complex sentences and to sing songs. After the surgery, he lost consciousness and became critically ill with irregular respiration. He was artificially ventilated for 10 days, and then recovered, with sequelae of right facial paresis and slight dysarthria. T1 weighted magnetic resonance image showed high intensities of the medial part of the inferior lobe of the cerebellum and medulla oblongata, which were interpreted as representing edema. This case illustrates that Chiari II malformation can become symptomatic after a VP shunt trouble.
