Ankara University School of Medicine Department of Neurosurgery, Ankara, Turkey Stereotaxy-guided surgery offers significant advantages in the treatment of lesions that cannot be localised reliably because of their smaIl size and/or lack of evident landmarks. A stereotactical1y-guided craniotomy and microsurgical resection technique was described for excision of a cavernous hemangioma. The technique provided advantages in better surgical orientation, precise localization and less invasiveness to the normal brain tissue when compared to the conventional free-hand neurosurgical techniques. Keywords : Cavernous angioma, minimally invasive, stereotactic craniotomy
