Objective To introduce the use of the StealthStation neuronavigator combined with preoperative computerized tomography (CT) in resection of intracranial cavernous angiomas (CAs) Methods The StealthStation neuronavigator was used to provide a realtime correlation of the operating field and the computerized images in 6 patients with CAs All patients suffered from epileptic seizures Four patients underwent keyhole surgery and 2 underwent small skin flap craniotomy The mean follow up was 4 5 months Results With the guidance of neuronavigator, lesionectomy associated with removal of hemosiderin deposition, gliosis and calcification was performed precisely The mean fiducial error was from 1 65?mm to 4 53?mm, the predicted accuracy at 10?cm was between 1 82?mm and 3 28?mm, and the sustained accuracy ranged from 0 50?mm to 3 45?mm Conclusion The StealthStation neuronavigator is reliable and accurate in the resection of CAs
