Some WD-related changes exhibit characteristic features on MRI, for instance 'face of the giant panda', which is seen in T2-weighted images of the midbrain and 'face of the miniature panda', which can be seen in the tegmentum region of the pons in the same sequence. Sometimes, T2-weighted images show hypointensity in the basal ganglia region as a result of deposition of iron in exchange for copper after chelation. MRI findings can be similar to those seen in several other disorders, including Leigh disease, hypoxic–ischemic encephalopathy, methyl alcohol poisoning, Japanese B encephalitis, and selective extrapontine myelinolysis caused by osmotic disequilibrium syndrome. It is essential, therefore, to correlate the imaging with clinical features and biochemical markers of WD.
