Abstract |
Spontaneous pain and painful overreaction to external
stimuli resulting from lesion confined central nervous
system (CNS) were named as thalamic syndrome. Thalamic
lesion and decreased regional cortical perfusion
thought to the pathogenesis of thalamic syndrome due to
decreased regional cortical perfusion thought to the
pathogenesis of thalamic syndrome due to decreased
function of thalamocortical tract. We performed Tc-99m-
HMPAO regional cerebral perfusion in 10 patients with
clinical diagnosis of thalamic syndrome due to thalamic
lesion or near the thalamic lesion at Yonsei University
Hospital, from January 1989 to August 1991. In contrast
to five patients with lesions near the thalamus who did
not show secondarily decreased perfusion at cerebral
cortex, four among the five patients with thalamic
lesions revealed decreased cortical perfusion in the
ipsilateral cerebral cortex on brain SPECT. These
Phenomena may suggest the loss of afferent activating
stimuli from the thalamus led to decreased neuronal
activity and the following hypoperfusion of cerebral
cortex, and might be one of the indirect signs for
suggesting presence of the thalamocortical tract. A
causal relationship between cortical hypoperfusion and
neuropsychological deficit is strongly suggested. |
