Trombóza mozgových vén

We decided to process this theme due to its nonspecific clinical features as they often cause diagnostic problems not only to clinicians but also to diagnostic. It is important to think of this disease mainly in young women who aminister hormonal contraception. Imaging methods play the crucial role in diagnostic of cerebral venous sinus thrombosis. The gold standard is a native CT of brain which shows the venous sinus thrombosis as a hyperdense lesion in the locus of the sinus („ dense triangle sign“), CT venography shows the sinus thrombosis as a defect in a contrast filling of the venous sinus („empty delta sign“). Other investigative metods are magnetic resonance imaging or MRA. In short we also mantion quite a rare but more serious thrombosis of profound cerebral veins v. cerebri magna-Galeni, vv. cerebri internae). The importance of early diagnostic and nonspecificity of syptomps is presented in 3 clinical cases that are the part of this work.

Key words: cerebral venous thrombosis, thrombosis of profound cerebral veins, „dense triangle sign“, „empty delta sign“
