49 Possible Causes for White Matter Abnormalities in the Periventricular Regions

  • Acanthosis Nigricans

    Cerebral magnetic resonance imaging revealed cortical atrophy and white matter abnormalities involving the fornix, corpus callosum, and parieto-occipital periventricular regions[ncbi.nlm.nih.gov] The presence of progressive cognitive and behavioral deterioration, combined with abnormal white matter signals on magnetic resonance imaging, led us to suspect X-linked adrenoleukodystrophy[ncbi.nlm.nih.gov]

  • Arthrogryposis-Renal Dysfunction-Cholestasis Syndrome

    The fluid-attenuated-inversion-recovery image (middle panel) shows abnormality of the periventricular white matter mainly in the occipital region (closed arrowheads).[ncbi.nlm.nih.gov]

  • Arthrogryposis Multiplex Congenita

    The fluid-attenuated-inversion-recovery image (middle panel) shows abnormality of the periventricular white matter mainly in the occipital region (closed arrowheads).[ncbi.nlm.nih.gov]

  • Neurogenic Arthrogryposis Multiplex Congenita

    The fluid-attenuated-inversion-recovery image (middle panel) shows abnormality of the periventricular white matter mainly in the occipital region (closed arrowheads).[ncbi.nlm.nih.gov]

  • Acute Intermittent Porphyria

    In addition to the distribution of cerebral white matter abnormalities, which affected regions particularly vulnerable to hypoxia-ischemia and excitotoxicity (eg, periventricular[doi.org] white matter), immature oligodendrocytes are highly susceptible to glutamate-dependent and other excitotoxic processes. 17 The homology of ALA with glutamate and aspartate[doi.org]

  • Adult Polyglucosan Body Disease

    Neuroimaging showed hyperintense white matter abnormalities on T2 and fluid attenuated inversion recovery sequences predominantly in the periventricular regions, the posterior[ncbi.nlm.nih.gov]

  • Neonatal Meningitis

    Region of interest were placed on periventricular white matter to quantify fractional anisotropy (FA) and mean diffusivity (MD).[ncbi.nlm.nih.gov] Decreased FA values in the periventricular white matter regions in neonatal meningitis confirm microstructural white matter injury.[ncbi.nlm.nih.gov] Even in those with normal outcome significant decrease in FA values were observed in right parietal and bilateral occipital white matter compared to controls.[ncbi.nlm.nih.gov]

  • Macrocephaly

    There is moderate white matter signal abnormality in the periventricular regions bilaterally.[medhelp.org] […] cerebellar asymmetry, cerebellar tonsil herniation, white matter and/or periventricular regions signal abnormalities with increased T2 signal intensity, thick corpus callosum[orpha.net] There is also a focal area of signal abnormality within the deep white matter of the right frontal lobe measuring 6x8 mm in size. Visible on T2 weighted imaging.[medhelp.org]

  • Alexander Disease

    The early T2-weighted image ( A ) shows extensive cerebral white matter abnormalities with partial sparing of the occipital region.[ajnr.org] Magnetic resonance imaging (MRI) of the brain in patients with Alexander disease typically shows signal abnormalities in the cerebral white matter, predominating in frontal[jamanetwork.com] There is a thin periventricular rim of low signal intensity ( arrows, A ). The basal ganglia and thalamus have an increased signal intensity.[ajnr.org]

  • Cytomegalovirus Infection

    In the other fetus, MR imaging added additional information by demonstrating abnormal signal intensity of the periventricular white matter in the occipital and frontal regions[ajnr.org]
