Therefore, in the present study, we use stable xenon computed tomography (xenon-CT) and/or 99mtechnetium hexamethylprophylene amine oxime (99mTcHMPAO) single photon emission computed tomography (SPECT) to determine whether the degree of cerebral hemodynamic disturbance correlates with the severity of motor impairment in 5 children with Sturge-Weber syndrome. We found that 5 patients had great variation in clinical progression and outcome, but MR imaging investigations all revealed extensive but stable abnormalities. rCBF, assessed by stable xenon-CT and/or 99mTcHMPAO-SPECT, showed perfusion defect in all subjects. However, the xenon-CT disclosed reduction of rCBF and cerebrovascular reactivity in patients with severe motor paralysis. The total CBF and rCBF detected by xenon-CT were improved after clinical status was stabilized. We conclude that the motor function impairment in patients with SWS appeared to better correlate with the degree of rCBF impairment than with the abnormalities in conventional neuroimaging. Therefore, the quantitative CBF study is one of the diagnostic modality of choice in evaluating the neurological status in patients with SWS. ? 2006. |
