Cerebral sinovenous thrombosis in a child with homocystinuria

Cerebral sinovenous thrombosis (CSVT) is a potentially fatal condition which can have multiple etiologies and varied presentation in children. Management of CSVT is incomplete without a search for possible etiology. Sebire et al (2005) found that the incidence of pediatric CVST is at least 0.67 per 100,000 children per year.1 We present an interesting case of a six-year old-boy with extensive CSVT who was diagnosed to be suffering from homocystinuria.
