105 Possible Causes for High Signal Intensities in Periventricular White Matter

  • Demyelinating Disease

    HIV encephalopathy…  In early stages of the disease, small areas of high signal intensity are seen on the t2-weighted sequences in the periventricular white matter that lack[slideshare.net]

  • Susac Syndrome

    Foci of high T2 signal intensity were noted in the corpus callosum and periventricular white matter ( Fig 2B ). Acute disseminated encephalomyelitis was suspected.[ajnr.org] In addition, high-signal-intensity changes are usually seen in the periventricular white matter and the deep gray matter [ 1 ].[ajronline.org] Again shown were multiple periventricular white matter lesions of high signal intensity on T2-weighted and FLAIR sequences (Figs. 1G , 1H , 1I , 1J ).[ajronline.org]

  • Multi-Infarct Dementia

    High signal intensity of the periventricular white matter, bilateral centrum semiovale, and right external capsule was found by fluid-attenuated inversion-recovery images[dovepress.com] A representative T2-weighted magnetic resonance image demonstrates multiple areas of high-signal intensity in the periventricular white matter bilaterally. Figure 2.[jamanetwork.com] Figure 1 Cerebral magnetic resonance imaging with fluid-attenuated inversion-recovery (FLAIR) showing high-signal intensity lesions in the periventricular white matter ( A[dovepress.com]

  • Infantile-Onset Ascending Hereditary Spastic Paralysis

    A, Note T2 high signal intensity in the periventricular white matter and corona radiata.[ajnr.org] The T2 high-signal-intensity lesions in the white matter were present in 6 of 9 patients (67%), all members of families I and III.[ajnr.org] Axial and coronal FLAIR images of patient 4 show high signal intensity in the posterior limb of both internal capsules ( white arrows, A ) and along the corticospinal tracts[ajnr.org]

  • Congenital Muscular Dystrophy

    There were high signal intensities throughout the centrum semiovale, periventricular, and sub-cortical white matters on T2-weighted images in a 4-year-old girl with merosin-negative[ncbi.nlm.nih.gov] At 1 year of age, the T2 weighted images showed diffuse high signal intensities throughout the centrum semiovale, and periventricular and subcortical white matter of the frontal[ncbi.nlm.nih.gov] High signal intensities are often observed throughout the centrum semiovale, periventricular, and sub-cortical white matters on T2-weighted images in MRI brain in children[ncbi.nlm.nih.gov]

  • Uremic Encephalopathy

    […] hypodensity on CT, low signal intensity on T1-weighted MRI and high signal intensity on T2-weighted MRI.[ncbi.nlm.nih.gov] white matter showed hypodensity on CT, low signal intensity on T1-weighted MRI and high signal intensity on T2-weighted MRI.[link.springer.com] In this 35-year-old woman with chronic glomerulonephritis and uremic encephalopathy, the basal ganglia bilaterally, internal capsules and periventricular white matter showed[ncbi.nlm.nih.gov]

  • Leigh's Disease

    MR imaging shows bilateral areas of abnormal high signal intensity on T2 weighted images in the basal ganglia, periventricular white matter, corpus callosum, peri-aqueductal[ijri.org]

  • CADASIL Syndrome

    A representative T2-weighted magnetic resonance image demonstrates multiple areas of high-signal intensity in the periventricular white matter bilaterally. Figure 2.[jamanetwork.com]

  • Adams-Oliver Syndrome 5

    Abstract In 1945, Adams and Oliver described congenital transverse limb defects associated with aplasia cutis congenita in a three-generation kindred with typical autosomal dominant inheritance and intrafamilial variable expressivity. Keywords Autosomal Recessive Inheritance Double Outlet Right Ventricle Skull Defect[…][link.springer.com]

  • Alexander Disease

    matter, which has normal signal intensity for unmyelinated white matter.[ajnr.org] Furthermore, a periventricular rim of high signal intensity on T1-weighted images and low signal intensity on T2-weighted images was apparent (Figure 2 b), and high intensity[jmedicalcasereports.biomedcentral.com] […] in the periventricular white matter.[ajnr.org]
