Five angiographically confirmed cases of ectasia of the basilar artery are described. Three patients presented with the classical combination of lower cranial nerve, bulbar, cerebellar and long tract signs and dementia, one as obstructive hydrocephalus with papilloedema, and the fifth with symptoms of chiasmal compression. All were above middle age and hypertensive. CT scanning demonstrated a partially calcified, tubular, enhancing prepontine and suprasellar mass in every case. Ventricular enlargement and cerebral parenchymal abnormalities were also present. These appearances are sufficiently characteristic to make invasive radiological investigation unnecessary.
本文描述了5例经血管造影确诊的基底动脉扩张病例。3例患者表现为典型的低位颅神经、延髓、小脑和长束征合并痴呆，1例表现为梗阻性脑积水伴视乳头水肿，第5例表现为视交叉受压症状。所有患者均为中年以上且患有高血压。CT扫描显示，每例患者均有一个部分钙化的管状桥前和鞍上强化肿块。还存在脑室扩大和脑实质异常。这些表现具有足够的特征性，无需进行侵入性放射学检查。
