Abstract | 「要旨」 99mTc-hexamethylpropyleneamine oxime(HMPAO)脳血流SPECTにて異常所見のみられた一過性チックの一例を経験した. 5歳女児. 4歳の頃より, 無意識に鼻を鳴らしたり両腕を小刻みに動かすようになった. 理学所見や頭部MRIでは異常所見は認めなかったが, 脳波上, 右側優位の前頭葉から頭頂葉にかけての異常波型を認めた. 99mTc-HMPAO脳血流SPECT像では, 右側優位で両側前頭葉, 両側頭頂葉, および右側頭葉, 右大脳基底核に高血流域が認められた. 一過性チックの診断, 病態把握に99mTc-HMPAO脳血流SPECTの有用性が示唆された. 「I. はじめに」 チック(tic)は, 突然におこる急激で常同的, かつ反復性の非律動的な不随意運動または発声と定義される. 小児期では4〜24%に認められ, 男児に多く, 男女比は3:1である. その症状, 経過によりいくつかの臨床型に分けられ, 持続期間が1年未満のものを一過性チック, 1年以上のものを慢性チックという. |

Abstract | [Summary] 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. |
