31 Possible Causes for Cortical Blindness, Prominent Sulci

  • Hypertensive Encephalopathy

    At admission, the patient was disorientated and presented with seizures and cortical blindness.[] 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[] Its common association with edema in the posterior areas of the brain (as seen above) often results in cortical blindness.[]

  • Cerebral Cortical Atrophy

    Imaging wise feature of cerebral cortical atrophy Generalized prominence of hemisphere cortical sulci on CT or MRI in mild cases.[] Characteristic features include prominent cerebral sulci (i.e. cortical atrophy) and v entriculomegaly (i.e. central atrophy) without bulging of the third ventricular recesses[] Characteristic features include prominent cerebral sulci (i.e. cortical atrophy) and ventriculomegaly (i.e. central atrophy) without bulging of the third ventricular recesses[]

  • 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[] While gyri and sulci had an almost normal US appearance, the periventricular gray matter featured prominently with increased echogenicity.[] 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[]

  • 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[] The image from day 258 shows prominence of cerebellar sulci (red arrow) and increased size of fourth ventricle.[] Examination Focal neurologic signs [Mostly related to occipital lobes] Aphasia Hemiparesis Ataxia Cortical blindness Limb apraxia Brainstem symptoms Head tremor Gait abnormalities[]

  • Subacute Sclerosing Panencephalitis

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

  • 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.[]

  • 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[] The fluid space between the cortex and the calvarium appears to be increased and the sulci/gyri may appear prominent. View prominent sulci/gyri.[] 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.[]

  • Chronic Daily Headaches

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

  • Atypical Teratoid Rhabdoid Tumor

    ., Norris, DG 1981 Transient cortical blindness secondary to vincristine therapy in childhood malignancies Cancer 47 37 40 Google Scholar 18.[] […] interpeduncular cistern and along the sulci adjacent to frontal lobes ( arrows ), representing disseminated leptomeningeal tumor.[] C, Axial (TR/TE, 700/22) fat-suppressed MR image shows prominent homogeneous contrast enhancement of the primary lesion as well as abnormal subarachnoid enhancement in the[]

  • 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[] […] 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[] Additionally, advances in cortical source localisation methods, including low resolution electromagnetic brain tomography, and beamforming have improved the accuracy in source[]
