ABSTRACT
This article reports a case of hyperthyroidism complicated with cerebral venous sinus thrombosis(CVST). A 33-year-old woman patient was admitted to the Department of Endocrinology due to hyperthyroidism. She developed convulsions of the legs, unconsciousness, and " epileptic" seizures in the early morning of the next day and was transferred to the Department of Neurology. The patient′s clinical manifestations and laboratory tests suggested hyperthyroidism, Graves′ disease complicated with CVST formation, internal jugular vein thrombosis, and venous acute cerebral infarction. After standard treatment for hyperthyroidism, anticoagulation, and reduction in intracranial pressure were given, the patient′s condition improved. After 3 months of follow-up, the patient had a good prognosis. Until now, 41 patients with hyperthyroidism complicated with CVST have been described in case reports. For patients with hyperthyroidism presenting with headaches, especially those with severe neurological symptoms such as epilepsy or hemiplegia, clinicians should be vigilant and conduct appropriate imaging evaluations to assess the possibility of CVST. Once the diagnosis of CVST is confirmed, treatment for both hyperthyroidism and CVST should be initiated simultaneously to achieve a favorable prognosis.
