Extensive cerebral Sinovenous Thrombosis in a 5 Year Old Girl, Following Mild Dehydration. (Case Report and Review of Literature).

Cerebral sinovenous thrombosis (CSVT) in children has rarely been reported in the literature, especially without underlying disorder. It has increasingly been diagnosed due to clinical awareness and sensitive neuroimaging techniques. The aim of this article was to report a case of cerebral sinovenous thrombosis without underlying disorder. We reported a 5 year old girl, presented with severe headache and seizure. She had a history of fever and diarrhea before the onset of headache. Neuroimaging showed evidence of CSVT on MRI and magnetic resonance venography. Investigations showed no inherited thrombophilia. The patient was treated with low molecular weight heparin (LMWH) which continued by warfarin. This case illustrated severe complications of dehydration in pediatrics without any evidence of underlying disorders.
