Syringomyelia and hydromyelia: magnetic resonance evaluation. 1984

K Pojunas, and A L Williams, and D L Daniels, and V M Haughton

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.

D013118 Spinal Cord Diseases Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord. Traumatic injuries, vascular diseases, infections, and inflammatory/autoimmune processes may affect the spinal cord.

D013595 Syringomyelia Longitudinal cavities in the spinal cord, most often in the cervical region, which may extend for multiple spinal levels. The cavities are lined by dense, gliogenous tissue and may be associated with SPINAL CORD NEOPLASMS; spinal cord traumatic injuries; and vascular malformations. Syringomyelia is marked clinically by pain and PARESTHESIA, muscular atrophy of the hands, and analgesia with thermoanesthesia of the hands and arms, but with the tactile sense preserved (sensory dissociation). Lower extremity spasticity and incontinence may also develop.
