Reversibility of hyperintense globus pallidus on T 1-weighted MRI follow- ing surgery for a portosystemic shunt in an 8-year-old girl.
An 8-year-old Japanese girl with a portosystemic shunt had shown hyperammonaemia since she was 3 years of age. MRI of her brain showed bilateral hyperintense globus pallidus. A portosystemic shunt was evident on US and angiography. She underwent surgical banding of the shunt, after which the lesion and clinical symptoms disappeared.
