Abstract
Anti-N-methyl-D-aspartate receptor encephalitis is a
life-threatening medical emergency that can be clinically misperceived as
Hashimoto’s encephalopathy. We present a case of
anti-N-methyl-D-aspartate receptor encephalitis in an otherwise
healthy young female with subclinical hypothyroidism without an associated
ovarian teratoma. She was first misdiagnosed as Hashimoto’s encephalopathy due
to delirium and behavioral changes, seizures, psychosis, and increased amount of
thyroid peroxidase and thyroglobulin antibodies in serum. Final diagnosis was
established by third week following presentation with the detection of
anti-N-methyl-D-aspartate receptor antibodies in her
cerebrospinal fluid. After treatment with intravenous immunoglobulin,
methylprednisolone, and amisulpride, she recovered significantly with minimal
sequelae at 3-week follow-up.
