Diffusion-weighted imaging abnormalities in wernicke encephalopathy: reversible cytotoxic edema?
BACKGROUND Wernicke encephalopathy (WE) is a metabolic disorder of the central nervous system resulting from vitamin B(1) deficiency. The exact mechanisms underlying the pathogenesis of the lesions in WE are not completely understood. Vitamin B1 deficiency is associated with intracellular and extracellular edema by glutamate(N-methyl-D-aspartate) receptor-mediated excitotoxicity. Conventional m...
متن کاملMR imaging with diffusion-weighted imaging in acute and chronic Wernicke encephalopathy.
Wernicke encephalopathy is a neurologic disorder that results from thiamine deficiency. It is associated with a classic triad of symptoms consisting of ataxia, ocular motor cranial neuropathies, and changes in consciousness. We report 3 cases of Wernicke encephalopathy in which MR imaging, including diffusion-weighted imaging, was performed at the onset and during follow-up. MR imaging findings...
متن کاملDiffusion-weighted MR imaging in hypertensive encephalopathy: clues to pathogenesis.
PURPOSE Hypertensive encephalopathy, a complex of cerebral disorders, including headache, seizures, visual disturbances, and other neurologic manifestations, is associated with a variety of conditions in which blood pressure rises acutely. It has been ascribed to either exuberant vasospasm with ischemia/infarction or breakthrough of autoregulation with interstitial edema. Diffusion-weighted MR ...
متن کاملValue of diffusion-weighted imaging in hypoglycemic encephalopathy
H is the most common metabolic disorder that may cause neonatal encephalopathy and result in permanent brain injury.1 Prompt diagnosis is important as urgent treatment may change the progression of the disease and the future prognosis. Conventional MRI is useful to demonstrate the signal changes that are prominent on the occipital lobes; however, MRI may not show the pathology in the very early...
متن کاملDiffusion‐weighted imaging characteristics of methotrexate‐induced acute encephalopathy
Methotrexate (MTX)-induced encephalopathy is a grave complication in patients with malignancies. The early diagnosis of acute encephalopathy was difficult by conventional computed tomography (CT), and T1- or T2-weighted magnet resonance (MR) imaging. We report that the diffusion-weighted (DW) imaging is useful for early detection of acute leukoencephalopathy.
