Cerebral sinovenous thrombosis in a toddler with iron deficiency anemia

Abstract

Cerebral sinovenous thrombosis (CSVT) is an increasingly recognized cause of neurological morbidity and mortality within the pediatric population. Unlike its manifestation in the adult population, CSVT in children has a broad and often multifactorial cause. Our case describes an 18-month-old young boy presenting to the emergency department twice during a 48-hour period with vomiting and lethargy. The child was found to have a sagittal sinus venous thrombosis caused by severe dietary iron deficiency anemia. Severe iron deficiency anemia has been linked to CSVT formation in several recent case reports.
