A 36 year old man from Kolkata was evaluated for the complaints of double vision and swaying while walking for 2 months. MRI showed a cavernous malformation in the brain stem. He was referred for radiotherapy as the location was eloquent. He was irradiated with fractionated radiosurgery keeping in mind the site of the lesion. 6 months after treatment he came for follow up. His gait was steady, his vision had improved and the MRI showed a dramatic decrease in the size of the lesion.
Vascular malformations of the brain pose threat by their propensity to bleed and cause neurological deficits. The brain stem location of this cavernoma makes surgery an obsolete option. The effective and conformal dose delivery helped in reduction in the volume of the malformation and improvement of symptoms.
Apollo Hospitals has treated more than 1000 cyberknife cases.
The patient was under treatment with Dr.Rathna Devi, senior consultant Radiation Oncologist.
