RT Journal Article SR Electronic T1 Concurrent hydromyelia and diastematomyelia. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 473 OP 477 VO 7 IS 3 A1 A E Schlesinger A1 T P Naidich A1 R M Quencer YR 1986 UL http://www.ajnr.org/content/7/3/473.abstract AB Hydromyelia was discovered in six of 13 patients with diastematomyelia. In one patient, hydromyelia affected only the segments of spinal cord above the diastematomyelia. In five patients, hydromyelia extended downward from the single cord into one or both hemicords. Because hydromyelia and diastematomyelia occur simultaneously, because they may produce very similar clinical changes, and because simultaneous or sequential surgical correction of both conditions may be necessary to achieve the best clinical result, the possibility of hydromyelia should be evaluated specifically in each patient demonstrated to have diastematomyelia.
