Female, 50 years old, history of epilepsy and laser ablation. Surveillance scan. Sequelae of prior right temporal depth electrode placement and right medial temporal laser ablation are seen. This includes several right-sided burr holes, small areas of curvilinear parenchymal gliosis, and a small T2 hyperintense mildly hemosiderin stained medial temporal ablation bed.Low lying cerebral tonsils compatible with Chiari I malformation are demonstrated. Otherwise, cerebral morphology and signal characteristics are within normal limits. No significant parenchymal edema or mass effect is detected. No acute intracranial hemorrhage or any abnormal extra axial fluid is seen. The ventricles are normal in size and morphology.
Expected findings status post right temporal depth electrode placement and right mesial temporal laser ablation.
