Learning objectives
To detect the early neurological changes and aid the patient to restrict the progression of the effects caused by various types of poisoning. Although toxic and metabolic brain illnesses are relatively uncommon conditions affecting the central nervous system, it is crucial to identify them because, if not treated promptly and appropriately, they can have disastrous consequences. Imaging is essential for establishing the most likely diagnosis, indicating the direction of further research, and offering prognostic data.
Background
CT scanning can be helpful in determining whether a toxin is present in a patient and how it affects them if poisoning is known to have occurred. A toxin's identification as the primary cause of these illnesses is crucial to preventing death or additional morbidity in these individuals. In stable cases, Magnetic resonance imaging (MRI) is done following a Computed Tomography (CT)Organophosphorous Poisoning:Mainly results in acute neurological dysfunction and respiratory distress. Anticholinesterases cause three distinct neurological syndromes following accidental or suicide exposure such as life-threatening...
Findings and procedure details
Organophosphorous Poisoning:CT shows hypoattenuation bilaterally in the basal ganglia. (2) MRI shows diffusion restriction with symmetrical T2 or T2 fluid-attenuated inversion recovery hyperintensities involving bilateral globus pallidus with extension to posterior limb of bilateral internal capsules and bilateral cerebellar hemispheres which indicates acute infarctsCarbon Monoxide Poisoning:CT shows low attenuation in the globus pallidusOn MRI, the medial portions of the globus pallidus appear as bilateral areas of low signal intensity on T1-weighted images and ofhigh signal intensity on T2-weighted and FLAIR imagesMethanol Poisoning:CT shows hypo-attenuation bilaterally...
Conclusion
Diverse perspectives on the indications and symptoms of common poisoning could enhance our comprehension of the fundamental mechanism, so aiding in the treatment of individuals who are acutely contaminated. (7)CT shows hypoattenuation bilaterally in various regions like basal ganglia ,globus pallidus ,putamen based on type of poisoning MRI gives a better resolution for cortical lesions than CT and gives better anatomical detail in the case of hemorrhage. (8) Although poisonings with arsenic and mercury are uncommon in the emergency department, early detection of these poisonings...
