Female, 45 years old, with refractory epilepsy, imaging for guidance during laser ablation. Limited imaging sequences were obtained for guidance during the laser ablation procedure. The laser probe tip has been placed in the anterior medial left temporal lobe via a left occipital approach. Postcontrast images demonstrate a ring of enhancement surrounding the tip of the laser probe. These findings occur in a background of volume loss within the left medial temporal lobe from prior laser ablation. No additional enhancing lesions are seen.
Expected findings are seen compatible with laser ablation of the anterior medial left temporal lobe.
