Abstract

<p>A 79-year-old woman presented with left hemiparesis 180 minutes before admission. She had a score of 9 points on the National Institute of Health Stroke Scale (NIHSS). MRI revealed acute infarction at the right radiate crown, and the right middle cerebral artery (MCA) occlusion. We performed intravenous infusion of tissue plasminogen activator and mechanical thrombectomy with Penumbra system. The occluded MCA was recanalized in 345 minutes from the onset. Her NIHSS improved to 0 point, and postoperative MRI showed that the infarction was localized to the right radiate crown and the putamen. She discharged on the tenth postoperative day with modified Rankin Scale 1. However, she felt unmotivated after 2 months from the onset, and MRI revealed new white matter lesion on right MCA perfusion area. On magnetic resonance spectroscopy, the lesion showed an increased rate of choline (Cho)/creatine (Cr), and a decreased rate of N-acetylaspartate (NAA)/Cr, which suggested loss and destruction of the neuronal cells. We reported a case of delayed white matter lesion after mechanical thrombectomy for middle cerebral artery occlusion. The long follow-up should be required for the detection of delayed changes on rescued penumbra area.</p>
