Cerebral venous thrombosis and Turner Syndrome: a rare reported association: Turner Syndrome is the only known viable chromosomal monosomy, characterised by the complete or partial absence of an X chromosome. It's the most common chromosomal abnormality in females. Apart from the well known dysmorphic features of the syndrome, it has been associated with a number of vascular pathologies; mainly involving the cardiovascular, renovascular, peripheral vascular and cerebrovascular system. It seems striking that thromboembolism is not considered as a feature of the syndrome. Most of the thromboembolism cases are related to the arterial vascular system; except for some rare reported portal venous thrombosis cases, peripheral venous thrombosis cases and to the best of our knowledge a single case of cerebral venous thrombosis with Dandy Walker malformation and polymicrogyria. We herein report a cerebral venous thrombosis case with Turner Syndrome. With no other found underlying etiology, we want to highlight that Turner Syndrome, itself, may have a relationship not only with the cerebral arterial vascular system pathologies but also with the cerebral venous thrombosis.
