Delayed restricted diffusion in carbon monoxide leukoencephalopathy.
to a wide range of neurological symptoms, ranging from headaches, dizziness and altered mental status to coma. The basis for this is thought to be hypoxia. Carbon monoxide competes with oxygen for binding to hemoglobin (Hb) and once bound, shifts the oxyhemoglobin dissociation curve to the left, thus impairing off-loading of oxygen molecules, leading to hypoxia . A sizable minority of CO poison...
متن کاملAcute demyelinating lesions with restricted diffusion in multiple sclerosis.
BACKGROUND AND OBJECTIVES It is widely accepted that typical acute demyelinating lesions in relapsing-remitting multiple sclerosis (RRMS) exhibit vasogenic edema with increased diffusion, as demonstrated by an increased apparent diffusion coefficient on MRI. In contrast, acute ischemic lesions demonstrate cytotoxic edema with restricted diffusion. Recent reports have documented selected cases o...
متن کاملRestricted diffusion on MR imaging of an acute cerebral lesion.
A 35-year-old woman with no previous medical history presented with a 3-day history of progressive left hemisensory loss, ataxia and hemiparesis. On neurological examination she had Medical Research Council (MRC) grade 4 pyramidal weakness, hyper-reflexia and mild incoordination on the left side. Sensory examination revealed decreased light touch, pain, temperature, vibration sense and proprioc...
متن کاملFate of Diffusion Restricted Lesions in Acute Intracerebral Hemorrhage
BACKGROUND Diffusion-restricted lesions on diffusion-weighted imaging (DWI) are detected in patients with intracerebral hemorrhage (ICH). In this study, we aimed to determine the fate of DWI lesions in ICH patients and whether the presence of DWI lesions is associated with functional outcome in patients with ICH. METHODS This prospective study enrolled 153 patients with acute ICH. Baseline MR...
متن کاملTeaching NeuroImages: 5-FU-induced acute leukoencephalopathy.
A 55-year-old man with carcinoma sigmoid colon (fluorouracil [5-FU]: cumulative dose of 6,600 mg/m; and oxaliplatinum: 245 mg/m) presented with encephalopathy and pancerebellar involvement 2 weeks after receiving a third cycle of chemotherapy. Brain MRI showed diffusion restriction in bilateral deep white matter, cerebellar peduncles, and splenium of corpus callosum (figures 1 and 2) suggestive...
