[A familial case of postural reflex disorder presenting high intensity area mainly in the globus pallidus on T1-weighted cerebral MRI without clear liver damage].
A 56-year-old woman was admitted because of chronic postural reflex disorder. A cerebral MRI revealed symmetrical high intensity area mainly in the globus pallidus on T1-weighted image. The symptom became manifested as gait disturbance from the age of 2 and gradually progressed. Her condition has, however, remained stable since the age of 26. The only sign of parkinsonism was akinesia. There was clear retropulsion but cerebellar ataxia was minimal, and dystonia was negligible. She had no dementia. Her parents were cousins and similar symptoms and high intensity area were found in one of her sisters. Routine liver function tests were normal, with only ICG elevated. Serum copper and ceruloplasmin were normal. A hereditary factor was suspected. There are no similar cases reported in the literature, thus we thought it worth reporting.
