The Usefulness of Electromagnetic Neuronavigation in the Pediatric Neuroendoscopic Surgery
A 12-year-old boy visited to the hospital due to intermittent syncope and headache. There was no abnormal finding on neurological examination, on past history and on other examination such as electrocardiography. However, brain MRI demonstrated about 8 cm sized cystic lesion on antrum of left lateral ventricle without hydrocephalus (). He underwent pinless EM image-guided neuroendoscopic septostomy and ventriculo-cystostomy through a right postcoronal burr hole on prone position. Postoperative brain CT demonstrated pneumocephalus on frontal horn of both lateral ventricles without any acute hemorrhagic or ischemic lesion (). Postoperative neurologic examination was non-specific. On follow-up, the size of cyst had decreased () and symptom improved.
