Face of the Giant Panda Sign-Wilson's Disease


'Face of the giant panda' sign consists of high signal intensity in the tegmentum except for red nucleus, preservation of signal intensity of the lateral portion of the pars reticulata of the substantia nigra and hypointensity of the superior colliculus. The exact pathogenesis of the marked hypointensity of the corpus striatum and superior colliculus in the T2 weighted MRI is possibly because of paramagnetic effects of the deposition of heavy metals.

Are there other known causes of the "panda face" besides Wilson's Disease? I was told that I have a "normal" brain MRI, but the panda face is clearly visible.
