42 Possible Causes for MRI Scan of the Brain Abnormal, Prominent Sulci

  • Cerebral Cortical Atrophy

    Imaging wise feature of cerebral cortical atrophy Generalized prominence of hemisphere cortical sulci on CT or MRI in mild cases.[] We did not enroll prospective participants who had additional neurological diagnoses that could cause abnormalities on brain MRI. 53 MS cases were taking disease-modifying[] Characteristic features include prominent cerebral sulci (i.e. cortical atrophy) and v entriculomegaly (i.e. central atrophy) without bulging of the third ventricular recesses[]

  • Alcohol Dementia

    The CT showed prominent sulci and gyri with deep white matter changes. There were no other abnormalities.[]

  • Leptomeningeal Metastasis

    The lesions were more prominent in the cerebellar sulci compared with in the cerebral sulci.[] A contrast-enhanced Magnetic Resonance Imaging (MRI) scan of the brain was obtained and revealed abnormal enhancement between the cerebellar folia, consistent with meningeal[] This revealed leptomeningeal metastases with contrast enhancement, more prominent in the cerebellar sulci, and changes consistent with acute hydrocephalus, which likely accounted[]

  • Normal Pressure Hydrocephalus

    NPH is suggested when ventricular dilation is out of proportion to the prominence of the sulci, but this is a subjective call.[] MRI or CT scan of the brain demonstrates ventricular enlargement disproportionate to cortical atrophy.[] The magnetic gait abnormality consists of very short steps with the appearance of the patient’s feet being stuck to the floor.[]

  • Glioblastoma Multiforme

    (a) On an axial nonenhanced CT scan, the sulci in the right hemisphere are normally prominent; on the left, the parietal sulci are effaced within a wedge-shaped region of[] These tests may include: Magnetic resonance imaging (MRI) and computerized tomography (CT) scans produce detailed images of the brain and spine and allow doctors to detect[] Computerized Axial Tomography (CT) scans and Magnetic Resonance Imaging (MRI) scans with and without contrast typically show an enhancing abnormality that "lights-up" after[]

  • Brain Stem Herniation

    The fluid space between the cortex and the calvarium appears to be increased and the sulci/gyri may appear prominent. View prominent sulci/gyri.[] Note the prominent sulci and gyri despite intracranial hemorrhage. 2.[] Prominence of sulci/gyri: When intracranial pressure increases, this compresses the cerebral cortex against the calvarium.[]

  • Communicating Hydrocephalus

    CT and MRI reveal bilateral extracerebral fluid collections, prominent sulci, normal ventricles, and no evidence of compression of the brain.[] Pre-contrast axial CT Sulci and gyri are very prominent due to cortical atrophy, unlike in obstructive hydrocephalus where there is effacement of sulci and gyri.[]

  • Obstructive Hydrocephalus

    Pre-contrast axial CT Sulci and gyri are very prominent due to cortical atrophy, unlike in obstructive hydrocephalus where there is effacement of sulci and gyri.[]

  • Progressive Multifocal Leukoencephalopathy

    The image from day 258 shows prominence of cerebellar sulci (red arrow) and increased size of fourth ventricle.[] Two weeks later, a new MRI showed progress of signal abnormality in the cerebellum and further extension now involving the brain stem and thalami.[] Despite these therapeutic measures, there was clinical deterioration with abnormal saccadic eye movements and failure of fixation, scanning dysarthria and more prominent gait[]

  • Marchiafava Bignami Disease

    Findings CT shows mild prominence of the ventricles and sulci consistent with mild generalized cerebral volume loss.[]
