Cerebral venous sinus thrombosis (CVT) is a rare disease that's associated with a wide variety of clinical signs and symptoms, and CVT is a potentially lethal condition. Iron deficiency anemia (IDA) as the cause of an adult case of CVT is very rare. We report here on a patient with CVT with intracerebral hemorrhage that was caused by IDA, and the patient was treated with hemodilution. We suggest that hemodilution should be considered as another therapeutic option for CVT with cerebral hemorrhage in a patient suffering with IDA.
