目的：确定社区老年人群中与中风无关的临床严重发现的发生率。材料和方法：神经放射科医生回顾了3672名65岁及以上老年人的MRI图像，这些人参加了一项以人群为基础的纵向心脑血管疾病研究。神经放射科医生提醒核磁共振成像领域中心注意潜在的严重异常。结果：在3,672幅图像中，(1.74%)发现临床严重异常，其中脑膜瘤19例(052%)，垂体腺瘤6例(0.16%)，海绵状畸形5例(0.14%)，血管狭窄8例(0.22%)，脑室瘤4例(0.11%)，脑室内肿块2例(0.05%)，硬膜下积液2例(0.05%)，其他肿瘤2例(0.05%)。只有9名患有这些异常的参与者需要手术。除1例脑膜瘤外，其余均为女性，且随着年龄的增长，脑膜瘤的患病率下降。结论：医生应警惕无其他症状的老年人可能存在严重的临床症状。
PURPOSE: To determine the prevalence of clinically serious findings unrelated to stroke on cranial magnetic resonance (MR) images in a population of community-dwelling elderly people.MATERIALS AND METHODS: Neuroradiologists reviewed MR images of 3,672 people aged 65 years and older who were enrolled in a longitudinal, population-based study of cardiovascular and cerebrovascular disease. The neuroradiologists alerted MR imaging field centers about potentially serious abnormalities. Clinical information was obtained from clinical examinations performed before MR imaging, hospital discharge summaries, and the field centers at which MR imaging was performed.RESULTS: On 3,672 image sets, 64 (1.74%) clinically serious abnonnalities were found Among the presumptive diagnoses were 19 meningiomas (052%) six pituitary adenomas (0.16%), five cavernous malformations (0.14%), eight vascular stenoses (0.22%), four aneurysms (0.11%) two intraventricular masses (0.05%), two subdural fluid collections (0.05%) and two other tumors (0.05%). Only nine participants with these abnormalities required surgery. All but one of the meningiomas were in women, and the prevalence of the tumor decreased with increasing age.CONCLUSION: Physicians should be alert to the possible presence of clinically serious conditions in otherwise asymptomatic elderly individuals.
