Diffusion-weighted imaging in posterior ischemic optic neuropathy.
Optic Neuropathy We read with interest the case report by Mathur et al in which they have described an acute ischemic event in the posterior part of the intraorbital optic nerve consequent to rhinocerebral mucormycosis and its early detection by diffusion-weighted MR imaging (DW-MR imaging). In this regard, we would like to report another similar case that we came across in our tertiary care in...
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 کاملDiffusion MR Imaging of Postoperative Bilateral Acute Ischemic Optic Neuropathy
A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed mark...
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...
متن کاملNonarteritic ischemic optic neuropathy.
BACKGROUND To describe the systemic and visual characteristics and prognosis in patients with nonarteritic ischemicoptic neuropathy (NAION) undergoing different treatments. METHODS Retrospective chart review was performed in Kaohsiung Veterans General Hospital patients from 1995-2005 with a clinical diagnosis of NAION, including nonarteritic anterior ischemic optic neuropathy and posterior is...
