Female, 45 years old, with epilepsy status post laser ablation on 8/18, three-month follow-up exam. Post ablation findings in the anterior medial left temporal lobe have evolved now demonstrating features of chronicity. Specifically, the rim of enhancement seen on the immediate postprocedural images has nearly completely resolved and there is further encephalomalacia of the amygdala and hippocampus. Cerebral morphology is otherwise unremarkable. A small area of gliosis at the site of the left occipital burr hole is unchanged. A few scattered small nonspecific foci of FLAIR hyperintensity in the cerebral hemispheres are also unchanged. No edema or mass effect is detected. No new pathologic intracranial enhancement is observed. Allowing for ex vacuo dilatation of the left temporal horn, the ventricular system remains within normal limits.
Expected evolution of post ablation findings in the left anterior medial temporal lobe.
