The Usefulness of Electromagnetic Neuronavigation in the Pediatric Neuroendoscopic Surgery
A 2-year-old boy visited with the complaint of prolonged headache after slipping down. On neurological examination, there was no specific finding. Brain CT showed about 6.5 cm sized cystic lesion on the right middle cranial fossa with midline shifting to the left side by 7 mm (). The neuroendoscopic cyst fenestration with the guidance of EM neuronavigation and the insertion of EVD catheter were performed. The postoperative brain CT showed multiple pneumocephalus on cisterns around brain stem and cyst. The boy discharged with the removal of EVD catheter and mild ptosis and medial gaze limitation on right eye. On the follow-up on out-patient department, the symptom improved and the size of the cyst decreased ().
