Female, 53 years old, with seizures. Evaluate for limbic encephalitis. T2 hyperintensity involving the mesial temporal lobe structures persists but has improved relative to the prior examination. The amygdala and hippocampi appear less swollen. The hippocampal cortex remains slightly hyperintense on DWI similar to prior. No associated pathologic enhancement is seen.No new parenchymal signal abnormality is seen. No evidence of significant generalized mass effect is detected. Previously demonstrated mild thickening and enhancement of the dura has resolved. No acute intracranial hemorrhage or any abnormal extra axial fluid collections are detected. The ventricular system is normal in size and morphology.
1.Interval improvement in signal abnormality and edema affecting the mesial temporal lobe structures. As before, the differential would include infection, limiting encephalitis or sequelae of seizure activity.2.Interval resolution of dural thickening and enhancement. No new intracranial lesions are seen.
