Pallidoreticular damage in acute carbon monoxide poisoning: diffusion-weighted MR imaging findings.
نویسندگان
چکیده
We describe a case of carbon monoxide poisoning that led to pallidoreticular damage and delayed leukoencephalopathy. Serial diffusion-weighted MR imaging was performed. A restricted water diffusion pattern was demonstrated in the globus pallidus and substantia nigra in the early stage. Diffusion-weighted imaging is useful for early identification of the effects of acute carbon monoxide poisoning.

Structural Findings in the Brain MRI of Patients with Acute Carbon Monoxide Poisoning
Background: Carbon monoxide (CO) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. Magnetic resonance imaging (MRI) has a well-recognized role in assessment of the severity of brain damage caused by CO poisoning. In this study, we aimed to present and analyze the structural abnormalities in the brain MRI and especially in diffusion weighted MRI (DWI) images in ...
متن کاملThe role of MR imaging in assessment of brain damage from carbon monoxide poisoning: a review of the literature.
SUMMARY The aim of this article is to review how MR imaging and associated imaging modalities provide clinicopathologic information on brain damage after carbon monoxide poisoning. Initially, many authors documented typical findings of conventional MR imaging in the gray matter structures such as the globus pallidus and in various regions of cerebral white matter. The focus of investigation has...
متن کاملAcute carbon monoxide poisoning: diffusion MR imaging findings.
During the acute stage of carbon monoxide poisoning, diffusion MR images obtained at b=1000 s/mm2 revealed high signal intensity lesions in the white matter, consistent with restricted diffusion. Low apparent diffusion coefficient values (0.18-0.34 x 10(-3) mm2/s) were noted in the affected white matter regions. Follow-up MR imaging performed 16 days later revealed disappearance of white matter...
متن کاملClinical significance of the pallidoreticular pathway in patients with carbon monoxide intoxication.
Whereas globus pallidus lesions resulting from carbon monoxide intoxication have been extensively described in the literature, the clinical significance of pallidoreticular lesions has rarely been mentioned. This study incorporated information from functional and structural imaging to explore the correlations of pallidoreticular lesions with parkinsonian features and neurobehavioural performanc...
متن کاملPallidoreticular lesion in carbon monoxide intoxication by gradient echo: report of a case with parkinsonism features and review of the literature.
PURPOSE Pallidoreticular damage was defined by lesions involving both the pallidum and the substantia nigra and was only reported in four cases after CO intoxication. CASE REPORT We report a patient with initial consciousness disturbances followed by parkinsonian features after carbon monoxide intoxication. The unique features in this patient included primary globus pallidus hemorrhage follow...
