is a type of Streptococci and is a rare cause of infectious endocarditis. The progression and outcomes of infectious intracranial aneurysms (IIAs) associated with this species are unknown due to a limited number of reported cases. A woman in her 20s with a sudden headache had a subarachnoid haemorrhage on a head CT scan. Cerebral angiography showed an aneurysm on the right middle cerebral artery. She was diagnosed with infectious endocarditis caused by and underwent parent artery occlusion. Despite initiating targeted antibiotic therapy, a new IIA developed and ruptured 14 days postadmission. A second parent artery occlusion was performed on the new IIA. Following 6 weeks of continued antibiotic therapy, she underwent mitral valve repair and was discharged with no neurological symptoms. Endocarditis caused by can lead to the delayed formation of an IIA. Endovascular treatment was effective for repeated ruptured IIAs.
是一种链球菌，是感染性心内膜炎的罕见病因。由于报告的病例数量有限，该物种引起的感染性颅内动脉瘤（IIA）的进展和结局尚不清楚。一位 20 多岁的女性突发头痛，头部 CT 扫描显示蛛网膜下腔出血。脑血管造影显示右侧大脑中动脉有一个动脉瘤。她被诊断为感染性心内膜炎，由 引起，并接受了主血管闭塞术。尽管开始了靶向抗生素治疗，但在入院后 14 天出现了新的 IIA 并破裂。对新的 IIA 进行了第二次主血管闭塞术。在继续抗生素治疗 6 周后，她接受了二尖瓣修复手术，出院时无神经症状。由 引起的心内膜炎可导致 IIA 的延迟形成。血管内治疗对反复破裂的 IIA 有效。
