摘要
３７例脊髓积水空洞症患者的磁共振成像（ＭＲＩ）资料显示大多数病例的病变范围较大，且位于脊髓中央，与第四脑室无明显的交通。３７例中有３４例伴ＣｈｉａｒｉⅠ型畸形。推测脊髓积水可能是本病的早期阶段，所以临床表现很轻且缓慢发展。大多数患者缺乏Ｃｈｉａｒｉ畸形的临床表现。因此，对于本病患者有必要施行颈枕区的ＭＲＩ检查。
Abstract We reviewed the MR imaging and the clinical data of 37 cases of Hydrosyringomyelia in this paper.MR imaging showed that the lesions in most cases were relatively large and located in the central parts of the spinal cords. None of them was found to have the communication between the fourth ventricle and the lesion, 34 of them were accompanied with Arnold-Chiari malformation, type 1. We presumed that the hydroimyelia might be the earlier state of this disease, This is why it manifests itself in a smaller size and developes slowly. Most of them did not have the symptoms and signs of the Arnold-Chiari malformation. It would be nesccesary for every such patient to have MR imaging of the cervico-occipital region in order to confirm or rule out the presence of such a malformation.
