31 Possible Causes for Cortical Blindness, Prominent Sulci

  • Hypertensive Encephalopathy

    At admission, the patient was disorientated and presented with seizures and cortical blindness.[ncbi.nlm.nih.gov] There was complete resolution of cerebral edema in all patients and mild interval prominence of the cerebral sulci, which can indicate cerebral volume loss, in three out of[bloodjournal.org] Its common association with edema in the posterior areas of the brain (as seen above) often results in cortical blindness.[casemed.case.edu]

  • Cerebral Cortical Atrophy

  • Canavan Disease

    The Y288 C variant was previously described in a child with macrocephaly, mild developmental delay, increased signal intensity in the basal ganglia, partial cortical blindness[ncbi.nlm.nih.gov] While gyri and sulci had an almost normal US appearance, the periventricular gray matter featured prominently with increased echogenicity.[ncbi.nlm.nih.gov] Late-onset krabbe disease (lokd) has first symptoms at ages 5 to 10 years, consisting of focal neurological signs, hemiparesis, cerebellar ataxia, cortical blindness, and[icd9data.com]

  • Progressive Multifocal Leukoencephalopathy

    A majority of these presentations occur from damage to cerebral visual pathways resulting in visual field defects, cortical blindness, and other disorders of visual association[ncbi.nlm.nih.gov] The image from day 258 shows prominence of cerebellar sulci (red arrow) and increased size of fourth ventricle.[doi.org] Examination Focal neurologic signs [Mostly related to occipital lobes] Aphasia Hemiparesis Ataxia Cortical blindness Limb apraxia Brainstem symptoms Head tremor Gait abnormalities[medcaretips.com]

  • Subacute Sclerosing Panencephalitis

    Other reported ocular findings in the disease are cortical blindness, hemianopsia, nystagmus, extraocular muscle paresis and optic atrophy.[ncbi.nlm.nih.gov] They can range from hyperintensities in the parietal and occipital region, brain stem lesions, and marked atrophy, causing prominence of sulci.[cureus.com] Cortical blindness in subacute sclerosing panencephalitis can be an early indicator for fulminant course.[ncbi.nlm.nih.gov]

  • West Nile Encephalitis

    Arrows indicate subtle enhancement in the sulci. B and C, FLAIR images show increased signal intensity in the sulci, more prominent on the left than on the right.[ajnr.org]

  • Brain Stem Herniation

    The posterior cerebral artery can get compressed by the uncus, giving rise to cortical blindness Radiological features of uncal herniation Uncus and medial temporal lobe displaced[derangedphysiology.com] The fluid space between the cortex and the calvarium appears to be increased and the sulci/gyri may appear prominent. View prominent sulci/gyri.[hawaii.edu] Cortical blindness resulting from this infarct is a false localizing sign because it gives the erroneous impression that the primary lesion is in the occipital lobe.[neuropathology-web.org]

  • Chronic Daily Headaches

    The scintillations are followed temporarily by a blind region, after the same retinotopic progression from central to peripheral visual fields.[doi.org] Finally ( viii ), we found that (like CSD) the spreading phenomenon did not cross prominent sulci (e.g., the parieto-occipital sulcus).[doi.org] Leao ( 2 ) first suggested a relationship between cortical spreading depression (CSD) and migraine aura, based on the uniquely slow spread of clinical and electrophysiological[doi.org]

  • Atypical Teratoid Rhabdoid Tumor

  • Amyotrophic Lateral Sclerosis

    Careful application of blind source separation, independent component analyses, and non-parametric statistics 25 have now dramatically reduced the level of noise and artefact[jnnp.bmj.com] […] periventricular topographic distribution, whereas McKee et al 8 noted that the initial pathological changes were perivascular and at the base of the sulci and in the later[doi.org] Additionally, advances in cortical source localisation methods, including low resolution electromagnetic brain tomography, and beamforming have improved the accuracy in source[jnnp.bmj.com]
