Diffusion 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 کاملRE: Diffusion MR Imaging of Postoperative Bilateral Acute Ischemic Optic Neuropathy
Dear Editor: We read with great interest, the case report on ischemic optic neuropathy (1). We would like to add a few points concerning the blood supply of the optic nerve and the correlation with the development of post-operative ischemic neuropathy. Actually, the perioperative or post-operative vision loss (postoperative ischemic neuropathy) is most likely due to ischemic optic neuropathy. I...
متن کاملDiffusion MR imaging in a case of acute ischemic optic neuropathy.
The purpose of this case report is to show the diagnostic potential of diffusion-weighted MR imaging in establishing the presence of ischemic optic neuropathy (ION). We report the MR imaging findings in a patient presenting with acute ION in whom diffusion imaging showed decreased water mobility as seen in patients with acute brain ischemia.
متن کاملDiffusion-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 کاملBilateral anterior ischemic optic neuropathy after bilateral neck dissection
PURPOSE The risk of visual loss after nonocular surgeries is very low, between 0.2% and 4.5%. According to the American Society of Anesthesiologists, ischemic optic neuropathy has been reported mostly after spinal surgery (54.2%), followed by cardiac surgery and radical neck dissection (13.3%). It may occur in association with some conditions that include systemic hypotension, acute blood loss ...
