Left thalamus infarction in the thalamotuberal artery perfusion area causing subcortical diaschisis and transcortical sensory aphasia
The thalamus is related to language function, and some thalamic stroke cases can cause aphasia [1]. However, most previous cases reporting thalamic damage-induced ipsilateral subcortical diaschisis and aphasia were hemorrhagic stroke [1,2]. Only a few left thalamus infarction cases showed cortical hypoperfusion concerned with the aphasia, but no single-photon emission computed tomography (SPECT) or thalamic nucleus data were available [3]. Thus, aphasia pathology due to cortical hypoperfusion following thalamus infarction, especially with respect to thalamic nuclei, is still unknown.

Crossed cerebellar diaschisis in Creutzfeldt-Jakob disease evaluated through single photon emission computed tomography
Sporadic Creutzfeldt-Jakob disease (sCJD) is the most common form of human prion disease; it is characterized as a transmissible spongiform encephalopathy. Previously, only two case reports have discussed crossed cerebellar diaschisis (CCD) and sCJD. Herein, we detected CCD in five patients with sCJD and four patients with genetic CJD through SPECT. The combined data of the nine patients further supported CCD when analyzed by 3D-SSP. CCD can occur in several disorders, including, stroke, epilepsy, and encephalitis.
