Cerebral vein and sinus thrombosis (CVT) is less encountered, compared to arterial stroke. Commonly witnessed symptoms are headache, nausea, vomiting, confusion, aphasia, seizures, cranial nerve dysfunction and motor or sensorial deficits. The diagnosis is accurately determined by the help of MRI and MR venography. Multiple risk factors associated with CVT are present. Venous thrombosis tends to occur when there is an imbalance between prothrombotic and thrombolytic processes. Case report. In this report, a patient with CVT extending from left transverse and sigmoid sinuses to jugular vein and diagnosed with diabetes mellitus (DM) during this period was discussed in light of literature. The 55-year-old man was evaluated in the neurology clinic with the complaints of headache, nausea, vomiting and blurred speech. On neurologic examination, he was diagnosed with sensorial aphasia and consequently, with DM over the hospital stay. On the cranial MR venography, CVT thrombosis was detected, extending from transverse and sigmoid sinuses to internal jugular vein. Decreased level of protein C and shortage of aPTT were found. Anticoagulant treatment was carried out. All complaints were improved. Conclusion. In our subject, the existence of decreased protein C and shortage of APTT, along with DM, is a situation to increase hypercoagulability and the risk of cerebral vein and sinus thrombosis.en10.4183/aeb.2011.283info:eu-repo/semantics/closedAccessCerebral venous sinus thrombosisdiabetes mellitusArticle72283290Q4WOS:000292125100014Q4
