Abstract:
We report a case of successful radiosurgical treatment of lesional epilepsy of mesial temporal origin. A patient presented with a 2-year history of medically intractable complex partial seizures associated with a mesial temporal angioma. Interictal scalp EEG and MEG showed focal epileptiform activity around the lesion. 99mTc-HMPAO-SPECT and 18F-FDG-PET demonstrated depressed blood flow and glucose metabolism in the corresponding temporal lobe. The patient underwent gamma knife radiosurgery for the causative lesion with a low marginal dose of 18 Gy. After treatment, the partial attack ceased without shrinkage of the lesion or peri-lesional parenchymal radiation injury.
