Introduction: Cerebral venous sinus thrombosis is a rare vascular disease affecting people regardless of their age. It is estimated that the disease is the cause of 1% of all cerebral strokes. Study design: The reported case has been described on the basis of the female patient’s medical record. Case study: The article describes a female patient, 47 years old, with arterial hypertension and metabolic syndrome who has been using hormonal contraceptives for 17 years. She sought medical attention due to headaches, the sensation of an alternate numbness in right and left extremities (for a month), vomiting (for a week) and high ESR levels. Upon admission, the patient underwent a neurological examination, yet apart from psychomotor retardation no pathology was detected. Computed tomography scan without contrast showed no lesions. Cerebral venous sinus thrombosis was confirmed only with additional examinations. Results: Despite the application of standard treatment methods, the patient’s condition did not improve. Focal and deficit symptoms that appeared during hospitalisation, resolved upon the inclusion of steroids in the treatment. Conclusion: The reported case testifies to difficulties in diagnosing and determining the aetiology of cerebral venous sinus thrombosis.
