Abstract
RATIONALE
Pancytopenia and epilepsia are rare complications of Graves' disease (GD). Muscle weakness is a physical sign of GD. It is extremely rare for GD patients to present 3 symptoms at the same time.
PATIENT CONCERNS
A 35-year-old female was admitted to hospital for dizziness for 1 day. The results of laboratory examination on admission showed pancytopenia and hypothyroidism. Her clinical manifestations include pancytopenia, epilepsy, and muscle weakness.
DIAGNOSIS
Graves' hyperthyroidism.
INTERVENTIONS
She received endotracheal intubation, ventilator, antithyroid drugs, and hormone therapy.
OUTCOME
The patient was discharged after treatment.
LESSON
Severe complications caused by GD are rare and require antithyroid therapy. Although glucocorticoid is not recommended by the guidelines, it can effectively improve thrombocytopenia.
