Technetium-99m ethyl cysteinate dimer dynamic and static single photon emission computed tomography in crossed cerebellar diaschisis.
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.
