Male, 33 years old, with seizures, status post laser ablation. Sequelae of prior left mesial temporal laser ablation are seen. The ablated tissue is mildly encephalomalacic and hemosiderin stained. Patchy enhancement within the ablated region persists but is smaller when compared to the immediate postprocedural examination. The left hippocampal head also demonstrates volume loss when compared to the right side and to preprocedural exams.Brain parenchymal morphology is otherwise unremarkable. No evidence of edema or mass effect is seen. No additional areas of pathologic parenchymal or extra-axial enhancement are observed. No acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles remain normal in size and morphology.
Expected findings are seen status post laser ablation treatment of the left mesial temporal lobe. Encephalomalacia and enhancement within the ablation bed is an expected finding. Also noted is some interval volume loss of the left hippocampal head.
