Abstract:
A 76-year-old woman with type 2 diabetes mellitus was admitted to our hospital with a complaint of involuntary movements of the limbs and face. Brain MRI demonstrated a bilateral high signal of putamen on the T1 weighted image, and she was diagnosed with diabetic chorea. She took a second dose of the COVID-19 vaccine 28 days before admission and lost her appetite. Consequently, her HbA1c level on admission decreased from 13.5% to 10.0% in 28 days. This case suggests that diabetic chorea could be induced by the rapid amelioration of a hyperglycemic state due to appetite loss after COVID-19 mRNA vaccination.
