Abstract

A 69-year-old man with a past history of right middle cerebral artery (MCA) occlusion had cerebral single photon emission computed tomography (SPECT) with technetium-99m ethyl cysteinate dimer (Tc-99m ECD). Dynamic SPECT in the super-early phase revealed normal uptake in the left cerebellum and hypoactivity in the right MCA territory. Conventional static SPECT revealed decreased cerebral blood flow in the right MCA territory and the left cerebellum, indicating crossed cerebellar diaschisis. Our SPECT studies revealed decreased retention of Tc-99m ECD in the cerebellum manifested as crossed cerebellar diaschisis.

摘要

一名有右侧大脑中动脉（MCA）闭塞既往史的69岁男性接受了锝-99m半胱氨酸乙酯二聚体（Tc-99m ECD）脑单光子发射计算机断层扫描（SPECT）。超早期动态SPECT显示左侧小脑摄取正常，右侧MCA区域活性减低。传统静态SPECT显示右侧MCA区域和左侧小脑脑血流量减少，提示交叉性小脑失联络。我们的SPECT研究显示，小脑内Tc-99m ECD滞留减少，表现为交叉性小脑失联络。
