Spinal stenosis: a review of 23 cases

Twenty-three cases of spinal stenosis suspected clinically and confirmed by computed tomography (CT) scanning are reviewed. The usually prolonged delay from the onset of symptoms to the time of diagnosis can be reduced by an awareness of the frequently bizarre, but usually bilateral clinical features. Confirmation of stenosis has required myelography, but CT scanning frequently may confirm the diagnosis without myelography and, being noninvasive, may facilitate earlier and more appropriate treatment.
