Gamma Knife Radiosurgery in Low Grade Glioma, decrease in T2 High Signal Volume

This, 35 years old man  has presented with  tonic clonic fits with loss of consciousness and sphincter control since five years, responded well to anti-epileptic medicines for three years. Progression in intensity and frequency of the tonic clonic fits observed in last two years, worst since one month. He also presented weakness of left lower limb since one month.Clinical examination has revealed left lower limb monoparesis grade 4/5.

MRI brain with contrast revealed  non enhancing mass in the right parietal para falcine region over motor strip with high T2 signals.  MR Spectroscopy revealed neoplastic activity within the lesion. He had Gamma Knife Radiosurgery with following prescription.

Target	Location	Prescription	Volume
A	Right parietal Glioma	12 Gy @ 50%	17.4 cm³

Low Grade Glioma: Follow up at 3 months shows about 25 % decrease in T2 high signal volume.
Pt. is clinically in static condition with fits controlled on medicine.
