Differential diagnosis of AOP infarction. Top of the basilar artery syndrome can lead not only to thalamic infarction, but also to additional characteristic cerebellar, brainstem and occipital lobe infarction (A1 and A2). For deep vein infarction caused by thrombosis, high density of bilateral internal cerebral veins (B1, black arrow) can be observed on head CT, and FLAIR shows angiogenic edema involving multiple arterial areas of thalamus (B2). Wernicke’s encephalopathy often implicates pulvinar (C1) with abnormal enhancement of papillary body (C2, white arrow). Diffuse midline glioma in bilateral thalamus with mass effect is hyperintense on FLAIR and isointensity on DWI (D1 and D2)
