【 摘 要 】

BackgroundHashimoto’s encephalopathy, also known as steroid responsive encephalopathy associated with autoimmune thyroiditis (SREAT) is an autoimmune neuroendocrine disorder marked by impaired brain function. It is a diagnosis of exclusion with variable nature of presentation and no gold standard investigation of choice.Case presentationHere, we report a case of SREAT in a 26-year-old female who presented to our Emergency Department with altered sensorium and generalised tonic clonic seizures. After thorough clinical examination and initial resuscitation, a provisional diagnosis of neuroglycopenic injury or possible encephalitis was made. Broad-spectrum antibiotics were initiated. Routine investigations and cerebrospinal fluid (CSF) study were inconclusive except for neutrophilic leucocytosis. Magnetic resonance imaging (MRI) depicted hyper-intense signal changes around bilateral hippocampus and thalamus. Serum anti-thyroid peroxidase (anti-TPO) was strongly positive while other serum and CSF autoantibodies were within normal limits. A diagnosis of SREAT was made and she responded brilliantly to systemic corticosteroids. Incidentally, anti-SSA (anti-Ro) and anti-SSB (anti-La) were positive and a possible association between Sjogren’s syndrome and SREAT was insinuated.ConclusionThere is a long list of differentials for SREAT and a proper diagnostic criteria must be followed to reach at a conclusion. It can be easily missed and remain underreported due to its overlapping nature and ambiguous presentation. Hence, clinicians must have high index of suspicion for the disease and optimal therapy should be initiated early to improve the long term mortality.
