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 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 کاملDiffusion-Weighted MR Imaging and Ischemic Stroke
Magnetic resonance imaging (MR) of ischemic cerebrovascular events with standard T1and T2-weighted spin-echo techniques is widely employed. Standard MR demonstrates vascular changes such as the absence of a flow void and the presence of arterial enhancement within 2-4 hours of ischemic stroke onset in some cases ( 1 ). The earliest morphologic change in the brain parenchyma, swelling, is visibl...
متن کاملposterior ischemic optic neuropathy following percutaneous nephrolithotomy
purpose: to report a case of posterior ischemic optic neuropathy (pion) following percutaneous nephrolithotomy (pcnl). patient and findings: a 57-year-old male who underwent pcnl because of renal stone was referred due to painless bilateral visual loss to the level of light perception immediately after the operation. the patient had history of diabetes mellitus, hyperlipidemia, and mild anemia....
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.
