In regions where tuberculosis is endemic, CT and MR are of limited use
in making the initial diagnosis of spinal tuberculosis. Their optimum
use is for monitoring the management of cases involving paralysis. CT
best evaluates the integrity of posterior bony structures which provi
de spinal stability and MR best demonstrates the content and extent of
the extradural mass that is causing the paralysis. Their use is illus
trated by three recent cases.
