Diagnostic MR imaging patterns in mitochondrial leukodystrophies

MR Imaging Patterns
Succinate dehydrogenase (complex 2) deficiency
Abnormalities in the brain stem, more specifically in the transverse pontine fibers
Abnormalities in the middle cerebellar peduncles
Abnormalities in the thalami
Succinate in MR spectroscopy
Complex 3 and 4 defects
Numerous small cysts with well-defined borders in the periventricular and deep cerebral white matter
Kearns-Sayre syndrome
Abnormalities predominantly affecting the directly subcortical cerebral white matter plus abnormalities in the globus pallidus and substantia nigra
NUBPL defects
T2 hyperintensity of the cerebellar cortex plus cerebral white matter abnormalities
