The Usefulness of Electromagnetic Neuronavigation in the Pediatric Neuroendoscopic Surgery
A 4-month-old male infant visited to the hospital due to incidentally detected intracranial cystic lesion. The baby was born with 2820 gram body weight at 38 weeks 5 days of gestation. The cystic lesion was detected on prenatal ultrasonography and the size enlarged on follow up examination. Brain MRI demonstrated about 8 cm sized interhemispheric multiloculated cystic lesion without enhancement and associated hypogenesis of corpus callosum, right lateral ventricular dilatation (). The baby underwent endoscopic cystic wall fenestration at multiple sites and insertion external ventricular drainage (EVD) catheter in the cyst. Postoperative brain CT showed decreased size of the cyst and subdural hygroma on bilateral frontoparietal region (). The baby discharged without any neurologic problem. But the cyst was enlarged again with the aggravation of ventriculomegaly on postoperative imaging study of 3 months (). Therefore, the endoscopic cyst fenestration and ventriculoperitoneal shunt was performed because the function of CSF circulation might be impaired. The size of cyst and ventricle decreased and the brain mantle has gotten thicker (). The boy has grown with normal development.
