RESUMO
BACKGROUND: To describe a rare presentation of ischemic stroke secondary to angioinvasive mucormycosis and endovascular retrieval of mycotic thrombus with stenting of the compressed vessel. SUMMARY OF CASE: We report a case of angioinvasive mucormycosis that externally compressed and invaded the internal carotid artery causing ischemic cerebral infarction. A sample of the thrombus was obtained using a stent retriever. Subsequent pathological analysis was shown to be consistent with the diagnosis of angioinvasive mucormycosis. The thrombosed and compressed segment was recanalized with the deployment of a stent. CONCLUSIONS: The endovascular placement of an expandable stent in the setting of angioinvasive mucormycosis restored good cerebral blood flow in a proximal internal carotid artery occlusion. The patient's aphasia resolved following this intervention. Artifacts of CT angiography may result in the overestimation of acute arterial occlusions. Endovascular carotid stenting may be a palliative measure in the setting of angioinvasive rhino-cerebro-orbital mucormycosis.

BACKGROUND: A 78-year-old woman was transferred directly to an ICU because of intracerebral hemorrhage. However, on careful review of the initial imaging, the likely diagnosis was ischemic stroke and reperfusion hemorrhage. METHODS: Case report was explained. RESULTS: The patient suffered significant reperfusion hemorrhage. A CT angiogram revealed contrast extravasation "spot sign" in the bed of the expanding hemorrhage and an occlusive thromboembolism distal to the initial ischemic insult. CONCLUSION: In this case of embolic ischemic stroke with reperfusion hemorrhage, contrast extravasation "spot sign" was associated with hematoma expansion.
