Magnetic resonance (MR) imaging of 13 proved cases of syringomyelia or hydromyelia and one case of myelomalacia is described. Most intramedullary cysts were evident on sagittal partial saturation recovery (PSR) images. One cyst containing viscous fluid was not demonstrated on PSR images, but was suggested on a sagittal spin echo image. The case of myelomalacia was indistinguishable from a syrinx on axial PSR and spin echo images. Not all cases of syringomyelia and hydromyelia had the typical MR appearance previously described in the literature. Atypical cysts, spinal cord degeneration, and tumors may have a similar appearance on MR.
本文描述了13例经证实的脊髓空洞症或脊髓积水病例以及1例脊髓软化症的磁共振（MR）成像情况。大多数髓内囊肿在矢状位部分饱和恢复（PSR）图像上清晰可见。一个含有粘性液体的囊肿在PSR图像上未显示，但在矢状位自旋回波图像上有所提示。在轴位PSR和自旋回波图像上，脊髓软化症病例与脊髓空洞难以区分。并非所有脊髓空洞症和脊髓积水病例都具有文献中先前描述的典型MR表现。非典型囊肿、脊髓变性和肿瘤在MR上可能具有相似的表现。
