After a review of the literature and an analysis of the clinical and radiographic features of basilar impression (b.i.) the authors describe 27 personal cases. In 6 b.i. was present in its pure form and in 21 it was associated with other anomalies at the cranio-vertebral junction. Because of the frequent misdiagnosis with multiple sclerosis or other chronic neurologic diseases and because of the possible improvement of symptoms following decompressive occipital craniectomy and cervical laminectomy, the importance of a correct and complete radiographic study of the cranio-vertebral junction in these cases is stressed.
在回顾文献并分析颅底凹陷症（BI）的临床和影像学特征后，作者描述了27例个人病例。其中6例为单纯的颅底凹陷症，21例与颅颈交界区的其他异常相关。由于常被误诊为多发性硬化症或其他慢性神经系统疾病，且枕下减压颅骨切除术和颈椎椎板切除术后症状可能改善，因此强调了对这些病例进行正确、完整的颅颈交界区影像学检查的重要性。
