123I-iomazenil（IMZ）单光子发射计算机断层扫描（SPECT）的早期和晚期图像分别反映脑血流和皮质苯二氮卓受体结合电位的分布。小脑交叉裂反映了大脑半球从左到右的代谢不对称。我们提出一个病例67岁的妇女谁发展短暂失语3天后发病的轻度急性硬膜下血肿。失语症期间的计算机断层扫描和磁共振成像未显示血肿扩大或任何新的病变。脑电图未见异常。失语症发生3天后，12i - imz SPECT的早期图像显示，相对于左小脑半球，右脑半球的放射性降低。同样的123I-IMZ SPECT的后期图像显示，相对于右脑半球，左脑半球的放射性降低。24 d后，失语症消失，123I-IMZ早期和晚期的小脑和大脑半球的左至右放射性不对称也得到了解决。
Early and late images of 123I-iomazenil(IMZ)single-photon emission computed tomography(SPECT)reflect distributions of cerebral blood flow and those of cortical benzodiazepine receptor binding potential, respectively. Crossed cerebellar diaschisis reflects left-to-right asymmetry of metabolism in the cerebral hemispheres. We present a case of a 67-year-old woman who developed transient aphasia 3 days after the onset of a mild acute subdural hematoma. Computed tomography scan and magnetic resonance imaging during aphasia did not show enlargement of the hematoma or any new lesions. Electroencephalography did not show any abnormalities. Early images of 123I-IMZ SPECT 3 days after the onset of aphasia revealed a decrease in radioactivity in the right cerebellar hemisphere relative to that in the left cerebellar hemisphere. Late images of the same 123I-IMZ SPECT displayed a decrease in radioactivity in the left cerebral hemisphere relative to that in the right cerebral hemisphere. Twenty-four days later, the aphasia disappeared and the left-to-right asymmetries of radioactivity in the cerebellar and cerebral hemispheres on the early and late 123I-IMZ SPECT images also resolved.
