Hyperthyroidism in childhood has a relative incidence of 5%. The presence of epilepsy secondary to thyrotoxicosis is very unusual. We report the case of a four-year old boy with thyrotoxicosis due to Graves' disease. This patient developed a generalized tonic-clonic seizure followed by left sided partial motor status epilepticus. The EEG was markedly abnormal. The EEG was normal after five months of the ablative therapy. At the present time the patient is seizure-free without any antiepileptic medication and receiving replacement therapy with thyroxin due to post-ablation hypothyroidism. We conclude that this is the first reported case with this association in our country. We discuss the possible pathophysiological mechanism involved in the development of seizures in this patient.

We describe the case of a young Hispanic female who presented with thyrotoxicosis with seizures and ischemic stroke. She was diagnosed with a rare vasculopathy - moyamoya syndrome. After starting antithyroid therapy, her neurologic symptoms did not improve. Acute neurosurgical intervention had relieved her symptoms in the immediate post-operative period after re-anastomosis surgery. However, 2 post-operative days later, she was found to be in status epilepticus and in hyperthyroid state. She quickly deteriorated clinically and had expired a few days afterward. This is the second case in literature of a fatality in a patient with moyamoya syndrome and Graves' disease. However, unlike the other case report, our patient had undergone successful revascularization surgery. We believe her underlying non-euthyroid state had potentiated her clinical deterioration. Case studies have shown positive correlation between uncontrolled hyperthyroidism and stroke-like symptoms in moyamoya syndrome. Mostly all patients with these two disease processes become symptomatic in marked hyperthyroid states. Thus, it may be either fluctuations in baseline thyroid function or thyrotoxicosis that potentiate otherwise asymptomatic moyamoya vasculopathy.
