6 Possible Causes for Hyperintense Lesions of the Globi Pallidi

  • Methylmalonic Acidemia

    On the diffusion-weighted MR images, the globi pallidi lesions were mildly hyperintense anteromedially and markedly hyperintense posterolaterally.[ajnr.org] Fast-FLAIR and T2-weighted FSE MR images revealed symmetrical, high signal in the globi pallidi ( Fig 1A ).[ajnr.org] On the diffusion-weighted (10,000/100 [TR/TE]) (b 1000 s/mm 2 ) MR image, the lesions were mildly hyperintense anteromedially and markedly hyperintense posterolaterally ([ajnr.org]

  • Isolated Complex I Deficiency

    The globi pallidi and white matter, still unmyelinated, are slightly hyperintense, with a tiny, focal hyperintensity in the left pallidum.[ajnr.org] A and B, Axial T2-weighted MR images (3000/120/1) obtained at first examination show hyperintense lesions in the substantia nigra ( arrow in A ) and medial thalamic nuclei[ajnr.org] C, Follow-up MR image (2028/120/2), obtained 2 years and 2 months later, shows lesions in the basal ganglia that involve both the putamina and the head of the left caudate[ajnr.org]

  • Infantile Beriberi

    […] and the globi pallidi in 3/22 (14%) of the infants.[link.springer.com] Results Hyperintense lesions on T2-weighted images were seen symmetrically in the putamen in all patients, in the caudate nuclei in 16/22 (73%), the thalami in 7/22 (32%)[link.springer.com]

  • Succinic Acidemia

    On the diffusion-weighted MR images, the globi pallidi lesions were mildly hyperintense anteromedially and markedly hyperintense posterolaterally.[ajnr.org] Fast-FLAIR and T2-weighted FSE MR images revealed symmetrical, high signal in the globi pallidi ( Fig 1A ).[ajnr.org] On the diffusion-weighted (10,000/100 [TR/TE]) (b 1000 s/mm 2 ) MR image, the lesions were mildly hyperintense anteromedially and markedly hyperintense posterolaterally ([ajnr.org]

  • ANE Syndrome

    The globi pallidi and white matter, still unmyelinated, are slightly hyperintense, with a tiny, focal hyperintensity in the left pallidum.[ajnr.org] A and B , Axial T2-weighted MR images (3000/120/1) obtained at first examination show hyperintense lesions in the substantia nigra ( arrow in A ) and medial thalamic nuclei[ajnr.org] C , Follow-up MR image (2028/120/2), obtained 2 years and 2 months later, shows lesions in the basal ganglia that involve both the putamina and the head of the left caudate[ajnr.org]

  • Hypotonia-Failure to Thrive-Microcephaly Syndrome

    The globi pallidi and white matter, still unmyelinated, are slightly hyperintense, with a tiny, focal hyperintensity in the left pallidum.[ajnr.org] A and B, Axial T2-weighted MR images (3000/120/1) obtained at first examination show hyperintense lesions in the substantia nigra ( arrow in A ) and medial thalamic nuclei[ajnr.org] C, Follow-up MR image (2028/120/2), obtained 2 years and 2 months later, shows lesions in the basal ganglia that involve both the putamina and the head of the left caudate[ajnr.org]
