hemiparkinsonism

Subcortical

and brainstem hemiatrophy accompanied by iron deposition in a patient with hemiparkinsonism-hemiatrophy syndrome: a case report. T2-weighted images of the patient. Subcortical and brainstem structures show atrophic changes in the left basal ganglia (a), thalamus (b), midbrain (c), and pons (d). Furthermore, dense hypointensity was seen in the left globus pallidus (a, b), with light hypointensity in the left substantia nigra (c)

Subcortical

and brainstem hemiatrophy accompanied by iron deposition in a patient with hemiparkinsonism-hemiatrophy syndrome: a case report. Neuroimaging of the patient. T2*-weighted gradient-echo sequences reveal the presence of hypointensities within the left globus pallidus (a1) and left substantia nigra (a2). The left globus pallidus shows no signal change on computed tomography scan (b) or T1-weighted image (c), while a low signal abnormality is seen on diffusion-weighted imaging (d). The [18F] N-(3-fluoropropyl)-2β-carbon ethoxy-3β-(4-iodophenyl) nortropane positron emission tomography scan shows no pathological striatal alterations (e)
