RESUMO
No case of moyamoya syndrome with bilateral posterior cerebral artery (PCA) occlusion has been reported in China so far as this disease is extremely rare. The case shown in this article is a middle-aged women who has a history of atrial fibrillation, hypertension and type 2 diabetes acutely attacked by this syndrome. The main clinical manifestations included binocular blindness, right limb weakness. Imaging findings showed bilateral acute cerebral infarction in the parietal occipital lobe, bilateral anterior cerebral artery and middle cerebral artery smoke angiogenesis, bilateral PCA occlusion with distal smoke angiogenesis. Considering the medical history of the patient, the cause of the disease was diagnosed as embolic stroke of undetermined source. The patient′s consciousness has been recovered and the limb weakness has been improved after active symptomatic treatment. However, the blindness did not see any improvements. This case report aims to improve clinicians′ understanding of bilateral PCA embolization in patients with moyamoya syndrome so the occurrence of cerebral infarction can be effectively prevented.
