The most common neuro-radiological finding of Wilson's disease on MR is bilaterally symmetric T2/FLAIR hyperintensity in the putamina (70%), caudate nuclei (60%), ventrolateral thalami (55-60%), and midbrain (50%) (31-41).
This showed high signal on T2 and fluid attenuation inversion recovery (FLAIR) in the posterosuperior putamina, seen to a greater extent on the left than the right (Fig.
A cranial CT scan performed on day 5 showed low attenuation confluent lesions in superficial white matter and putamina consistent with acute toxic edema with high attenuation foci in the putamina consistent with hemorrhage (Figure-A).
