Abstract:
Toxic encephalopathy is a term used to describe a group of diseases that are caused by poisoning with a variety of harmful substances. The main clinical manifestation of these diseases is damage to the central nervous system. Previously reported cases of selenium poisoning had only general clinical manifestations, and head imaging changes were rarely reported. This article reports a 58 year-old selenium-poisoned female patient who had been taking a selenium-containing dietary supplement for a long period of time and subsequently developed neurological impairment. The head magnetic resonance imaging indicated the presence of irregular and abnormal signals in the midbrain and cerebellum. The objective of reporting this case is to show the neurological manifestations of selenium toxic encephalopathy and to provide references for the clinical diagnosis and treatment of this disease, as well as the standardized utilisation of selenium-containing supplements.
