We report a case of transient tic disorder with abnormal findings on 99mTc-HMPAO SPECT. The patient was 5-year-old girl with vocal and motor tic. There was no evidence of structural abnormality on magnetic resonance imaging (MRI). Electroencephalogram (EEG) showed spikes and sharp waves on both frontal lobes and parietal lobes (left-side dominant). 99mTc-HMPAO SPECT demonstrated focal regions of hyperperfusion in the both frontal lobes, both parietal lobes and right temporal lobe corresponding to the abnormal findings detected by EEG. It also demonstrated an area of hyperperfusion in the right basal ganglia. It is suggested that 99mTc-HMPAO SPECT is useful for the diagnosis and the understanding of the clinical state of tic disorder.
我们报告一例99mTc-HMPAO单光子发射计算机断层扫描（SPECT）有异常发现的短暂性抽动障碍病例。患者为一名5岁女童，有发声和运动抽动症状。磁共振成像（MRI）未显示结构异常。脑电图（EEG）显示双侧额叶和顶叶（左侧为主）有尖波和锐波。99mTc-HMPAO SPECT显示双侧额叶、双侧顶叶和右侧颞叶有与EEG检测到的异常发现相对应的灌注增加灶。它还显示右侧基底节有一个灌注增加区。提示99mTc-HMPAO SPECT对抽动障碍的诊断和临床状态的理解有用。
