摘要
本文研究了91例脊髓空洞症的磁共振成像,着重对空洞内胶质增生的MRI表现及其临床意义进行探讨。胶质增生常出现于较大的空洞内,可有多种形态表现,条带状胶质增生在空洞内形成间隔将其分成几个腔。手术治疗时应将这些间隔切开并置多根引流管才能取得良好疗效;团块状胶质增生的形态信号改变与脊髓内肿瘤相似,但注射Gd—DTPA后不强化,因此,增强后成像有助于二者的鉴别。
Magnetic Resonance Imaging (MRI) of 91 patients with syrongomyelia were reported. The stress was put on the study in MRI appearance and clinical significance of gliosis in the syrinx cavities. The gliosis may expressed variart mophologicai changes, and were often demonstrated in the syringomyelia with longer diametes and length. It may appeared as septatoins within the cavity and the syrinx cavity were(?)eparated into two or several cavities. This septations should be cut off at the surgical treatment and multiple drainage tubes should be used for the separated syrinxs. The gliosis may expressed as a focal solid mass and its morphological change and signal intensity is similar to the spinal tumors. The gliosis mass usually is not enhanced by Gd—DTPA, so that postcontrast Imaging may be useful to differential it from the tumors.
