16 Possible Causes for MRI Scan of the Brain Abnormal, Optic Disc Pallor, Visual Field Test Abnormal

  • Leptomeningeal Metastasis

    […] of optic disc and optical coherence tomography showed an atrophy of temporal retinal nerve fiber layer Click here to view Discussion LC, also referred to as carcinomatous[] A contrast-enhanced Magnetic Resonance Imaging (MRI) scan of the brain was obtained and revealed abnormal enhancement between the cerebellar folia, consistent with meningeal[] Visual field in automated perimetry test showed a cecocentral scotoma after 6 months of treatment Click here to view Figure 4: After 6 months of treatment, he had a temporal pallor[]

  • Idiopathic Intracranial Hypertension

    Visual field tests were normal in four eyes.[] pallor in the presence of continuing swelling 24, 25 (Fig. 3 ).[] Imaging tests Your doctor may perform a CT or MRI scan of your brain to look for signs of spinal fluid pressure.[]

  • Suprasellar Tumor

    Neurological examination revealed pallor of the left optic disc. There was no extraocular dysmotility or facial numbness.[]

  • Multiple Sclerosis

    The evolution of temporal optic disc pallor (arrow) after left optic neuritis.[] At that time, symptoms and signs of right-sided sensory disturbance together with a history of uniocular central visual loss and, on fundoscopy, pallor of both optic discs[] During this time, patients develop optic atrophy, with temporal optic disc pallor (see image below).[]

  • Malignant Glioma

    […] nerve head (although disc pallor may also be observed with posterior lesions).[] Initial signs and symptoms of malignant gliomas include severe retro-orbital pain, unilateral or bilateral vision loss, and, typically, massive swelling and hemorrhage of the optic[]

  • Papilledema

    Visual fields can be tested more formally by an ophthalmologist using vision grids.[] Atropic Papilledema  Onset of optic disc pallor (secondary optic atrophy) .  Decrease in disc haemorrhage.  Narrowing of blood vessels and their ensheating.  Optic disc[] disc elevation and blurred margins, but no hemorrhages or cotton wool spots In atrophic phase (optic nerve axons have died), optic disc shows mixture of pallor and swelling[]

  • Optic Neuropathy

    With this information, it is possible to correlate the degree of slimming within these layers to abnormalities in the visual fields.[] , and (f) development of optic disc pallor, usually within 6-8 weeks.[] MRI scans of the brain are normal and those of the optic nerves often, but not always, show high signal abnormalities which enhance.[]

  • Occipital Lobe Tumor

    With maturity, more rigorous computerized visual field tests are possible.[] These let doctors see inside the brain and identify any areas that look abnormal. Although both are painless, they do require children to be still.[] […] tumor, a neurologist recommends some or all of these additional diagnostic tests: computed tomography scan (CT scan) to reveal brain abnormalities magnetic resonance imaging[]

  • Neuromyelitis Optica

    Two patients who presented with clinical optic neuritis also had abnormal VEPs and optic disc pallor.[] [Ann Neurol 50 (2001) 121] were selected to perform MRI scanning of the brain, spinal cord and optic nerves.[] In the series reported by Pittock et al. 14, almost half of the patients with brain MRI abnormalities had a normal scan on first evaluation, only disclosing brain abnormalities[]

  • Retrobulbar Neuritis

    For this same reason the difference between perceptual delays for two sites in the visual field (T s) may also be abnormal.[] Loss of colour vision and optic disc pallor are commonly found in asymptomatic patients with dominant optic atrophy.[] All 3 patients who developed MS had an abnormal brain MRI scan at their initial presentation of optic neuritis.[]
