Hashimoto Encephalopathy as a Complication of Autoimmune Thyroiditis.

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.
