Intraorbital optic nerve signal hyperintensity on magnetic resonance imaging sequences in perioperative hypotensive ischemic optic neuropathy.
نویسندگان
چکیده
A 61-year-old man experienced severe bilateral posterior ischemic optic neuropathy after cardiac bypass surgery. Routine magnetic resonance imaging sequences were normal, but diffusion-weighted and fluid-attenuated inversion recovery (FLAIR) sequences showed abnormal hyperintensity within both intra-orbital optic nerves. This imaging abnormality has not been previously reported in this setting.

Magnetic resonance imaging of feline eye
The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...
متن کاملReduced apparent diffusion coefficient in neuromyelitis optica-associated optic neuropathy.
I n their excellent review of neuromyelitis optica (NMO), Morrow and Wingerchuk (1) discuss the criteria that distinguish this condition from multiple sclerosis. Here, we describe diffusion-weighted magnetic resonance imaging (DWI) of the optic nerve in a patient with NMO-associated optic neuropathy. A 21-year-old man developed vision loss in the right eye that was diagnosed as optic neuritis. ...
متن کاملMRI findings in Post-operative Bilateral Posterior Ischemic Optic Neuropathy.
A 62-year-old female complained of vision loss following multiple abdominal surgeries for mesenteric ischemia. The patient’s visual acuity was no light perception (NLP) in the right eye and hand motion (HM) at 1’ in the left eye. Both pupils were unreactive and no relative afferent pupillary defect was noted. Anterior segment and fundus examination were unremarkable. T1 and T2 weighted MRI imag...
متن کاملUnilateral optic neuropathy following subdural hematoma: a case report
INTRODUCTION Unilateral optic neuropathy is commonly due to a prechiasmatic affliction of the anterior visual pathway, while losses in visual hemifields result from the damage to brain hemispheres. Here we report the unusual case of a patient who suffered from acute optic neuropathy following hemispherical subdural hematoma. Although confirmed up to now only through necropsy studies, our case s...
متن کاملHyperintense Optic Nerve due to Diffusion Restriction: Diffusion-Weighted Imaging in Traumatic Optic Neuropathy.
BACKGROUND AND PURPOSE Abnormal signal intensity of the optic nerve due to diffusion restriction may be seen in traumatic optic neuropathy. In addition to evaluating optic nerve hyperintensity on diffusion-weighted imaging, we compared the group differences of ADC values between the injured and uninjured contralateral nerve and identified the relation between measured ADC values and admission v...
