Three patients with unusual presentations of basilar artery ectasia are described: subarachnoid hemorrhage was manifest in one and autonomic dysfunction developed in the other two. Aneurysmal rupture was the cause in the first patient, while compression of the brainstem and/or of the baroreceptor afferences of the IXth and Xth cranial nerves is postulated to be responsible for the symptoms found in the other two. Basilar artery aneurysms should be considered in cases with subarachnoid hemorrhage or autonomic dysfunction, particularly when diagnostic procedures fail to disclose other possible etiologies.
本文描述了3例基底动脉扩张的特殊表现：1例表现为蛛网膜下腔出血，另外2例出现自主神经功能障碍。第1例患者病因是动脉瘤破裂，而另外2例患者的症状推测是由于脑干受压和/或第IX和第X颅神经的压力感受器传入神经受压所致。对于出现蛛网膜下腔出血或自主神经功能障碍的病例，尤其在诊断程序未能发现其他可能病因时，应考虑基底动脉动脉瘤。
