title: [Angiographically documented hemorrhagic transformation of embolic stroke: A case report].
abstract: A 81-year-old man with rheumatoid vasculitis presented with total aphasia followed by right hemiplegia. The NIHSS score was 24. Diffusion weighted magnetic resonance imaging (DWI) demonstrated an acute infarct in the left middle cerebral artery (MCA) territory, and magnetic resonance angiogram (MRA) revealed left MCA M1 occlusion. We administrated recombinant tissue plasminogen activator (rt-PA) at 132 min after symptom onset, but symptom was not improved. Emergency neuroendovascular recanalization was conducted with Penumbra(®) system. After MCA was recanalized partially, extravasations appeared on left lenticulostriate arteries territory at 376 min from symptom onset. Multiple extravasations spread over perforating branches, and ventricular rupture recognized angiographically. After the procedure, head CT demonstrated hematoma on left basal ganglia territory with intraventricular bleeding. Rheumatoid vasculitis might affect hemorrhagic infarction in emergency neuroendovascular recanalization procedure, and careful choice of treatment would be required.
