Oral contraceptives caused venous sinus thrombosis complicated with cerebral artery infarction and secondary epileptic seizures

RATIONALE Venous sinus thrombosis is a special type of cerebrovascular disease. Its incidence is low and its symptoms are lack of specificity. And its early diagnosis and treatment are very difficult. PATIENT CONCERNS This paper reported a rare case of a 43-year-old female who presented with cerebral venous thrombosis (CVT) complicated with cerebral artery infarction and secondary epileptic seizures due to oral contraceptives. DIAGNOSES The final diagnosis was intracranial venous sinus thrombosis, acute cerebral infarction in the left parietal lobe, intracranial hypertension syndrome, and continuous epilepsy. INTERVENTIONS The patient recovered well after active treatment. OUTCOMES Three months after discharge, the muscle strength of the right limb of the patient was significantly increased, and no recurrence of neurological symptoms occurred. LESSONS In conclusion, early diagnosis, correct evaluation, and standard treatment are still important challenges for CVT. Active treatment is recommended.
