Findings are most suggestive of which of the following: A. Artery of Percheron infarct B. Carbon monoxide poisoning C. Hypoxic ischemic injury D. Deep vein thrombosis
D, Deep vein thrombosis. Briefly, an artery of Percheron infarct involves the ventromedial thalami. Carbon monoxide may involve the globi paladi but the thalami would not be expected to be involved.
Non-contrast CT demonstrates increased density within the deep cerebral veins bilaterally. There is also noticeable hypoattenuation of the bilateral thalami and basal ganglia related to edema.
