Unilateral Thalamic Venous Infarction in an Infant: A Rare Presentation of Bilateral Deep Cerebral Venous Thrombosis

Figure 2

MRI obtained to confirm deep cerebral venous thrombosis and left thalamic infarction. DWI and ADC imaging ((a), (b), (g), and (h)) shows restricted diffusion in the anteromedial left thalamus without distinct territorial boundaries in relation to venous ischemia. T2 FLAIR hyperintensity ((c), (d), (i), and (j)) shows surrounding edema related to the infarction. GRE image (f) shows dark signal loss suggestive of petechial hemorrhage around the area of ischemia. GRE image (l) shows linear signal drop in the posteromedial surface of the left thalamus, highly suggestive of thrombus within a venous structure, likely part of the left internal cerebral vein.
