Restricted diffusion in the basal ganglia (and thalami) is seen in a variety of conditions, often associated with other signal abnormality of the basal ganglia. Care should be taken to confirm that increased signal on DWI actually represents restricted diffusion rather than merely T2 shine through.

It is important to note that each entity listed below has a variable pattern of involvement of the deep grey matter structures (basal ganglia and thalami).

Causes include :

acute exposure to respiratory chain metabolic toxins
- carbon monoxide poisoning
Wilson disease (early)
hyperammonemia
- acute hepatic decompensation in cirrhosis
- ornithine transcarbamylase deficiency
hypoglycemia
hypoxic ischemic encephalopathy
osmotic demyelination
Wernicke encephalopathy
Creutzfeldt-Jakob disease
deep cerebral venous thrombosis
arterial infarction
- top of basilar syndrome
- perforator infarct (usually unilateral)
- artery of Percheron infarct
flavivirus encephalitis
- Japanese encephalitis
