RT Journal Article SR Electronic T1 An unusual cause of cerebral venous sinus thrombosis. Paroxysmal nocturnal hemoglobinuria JF Neurosciences Journal JO Neurosciences (Riyadh) FD Prince Sultan Military Medical City SP 267 OP 269 VO 16 IS 3 A1 Bi, Sheng A1 Fan, Jia A1 Dong, Jing A1 Liu, Qun YR 2011 UL http://nsj.org.sa/content/16/3/267.abstract AB Cerebral venous sinus thrombosis caused by paroxysmal nocturnal hemoglobinuria is uncommon. Our case is a 44-year-old woman who presented with a 2 day history of headaches, nausea, and seizures followed by a Todd’s paresis; she had been diagnosed as paroxysmal nocturnal hemoglobinuria for 4 years. A magnetic resonance venography revealed extensive thrombosis of the cerebral venous sinus. She received antithrombotic treatment with a good outcome. We highlight paroxysmal nocturnal hemoglobinuria as the reason for the cerebral venous sinus thrombosis. The treatment of cerebral venous sinus thrombosis caused by paroxysmal nocturnal hemoglobinuria should be individualized.
