Decreased diffusion in central pontine myelinolysis.
نویسندگان
چکیده
Two patients with central pontine myelinolysis (CPM) were studied with diffusion-weighted MR imaging 1 week after onset of tetraplegia. In both patients, affected white matter showed hyperintensity on diffusion-weighted images associated with a decrease in apparent diffusion coefficient (ADC) values. In one patient studied serially, ADC values normalized by 3 weeks after tetraplegia. Early in the clinical course, diagnosis of CPM can sometimes be difficult. Hyperintensity on diffusion-weighted images may therefore have diagnostic utility. Decreased lesional ADC values support the notion that CPM is a consequence of relative intracellular hypotonicity.

Central pontine myelinolysis after liver transplantation: MR diffusion, spectroscopy and perfusion findings.
Magnetic resonance spectroscopy (MRS) and perfusion of central pontine myelinolysis (CPM) have been rarely reported. One case of CPM that developed after liver transplantation was analyzed with serial diffusion-weighted imaging (DWI), MRS and MR perfusion. During the acute phase, a pontine lesion showed an obvious high-signal intensity on DWI with decreased apparent diffusion coefficient value,...
متن کاملEarly diagnosis of central pontine myelinolysis with diffusion-weighted imaging.
Central pontine myelinolysis (CPM) occurs in the setting of rapidly corrected hyponatremia, especially in chronically debilitated patients. Conventional CT and MR imaging findings lag the clinical manifestations of CPM. We present a case in which restricted diffusion was identified within the central pons by using MR diffusion-weighted imaging within 24 hours of onset of patient tetraplegia and...
متن کاملCorticospinal Tract and Pontocerebellar Fiber of Central Pontine Myelinolysis
Central pontine myelinolysis is a rare neurologic disorder that is defined by demyelination of longitudinally descending tracts and transversly crossing fibers in the basis pontis. Frequently observed clinical manifestations of this disorder include sudden weakness, dysphagia, loss of consciouness and locked-in syndrome. However, there have been a few studies that reported a benign course of th...
متن کاملCentral pontine myelinolysis following orthotopic liver transplant: association with cyclosporine toxicity.
Central pontine myelinolysis can occur after orthotopic liver transplantation leading to high mortality and serious morbidity. In our case, central pontine myelinolysis was associated with wide fluctuations in cyclosporine levels during an episode of hypocholesterolaemia, which may have precipitated central pontine myelinolysis.
متن کاملCentral pontine myelinolysis after orthotopic liver transplant-a rare complication.
Central pontine myelinolysis is a rare but devastating cause of morbidity and mortality after orthotopic liver transplant. The exact cause of central pontine myelinolysis is uncertain. However, rapid correction of hyponatremia has been described as a major factor. We describe a patient with central pontine myelinolysis after orthotopic liver transplant in the absence of significant hyponatremia...
