Objective: To present a case of Hashimoto encephalopathy as a complication of autoimmune thyroiditis.
Clinical presentation and intervention: A previously healthy 56-year-old female presented with rapidly progressive cognitive decline and visual hallucinations. Being a diagnosis of exclusion, Hashimoto encephalopathy required an extensive laboratory and diagnostic workup, which was done over the course of a 15-day hospitalization. The patient recovered after initial treatment with intravenous methylprednisolone and was then switched to prednisone p.o.
Conclusion: This case report illustrates the importance of awareness for Hashimoto encephalopathy, as it remains one of the few easily treatable and reversible causes of rapid cognitive decline.
Keywords: Autoimmune thyroiditis; Hashimoto encephalopathy; Steroid-responsive encephalopathy.
