Background and purpose: Cerebral venous thrombosis (CVT) is the thrombosis affecting cerebral veins and sinus and is a rare condition. The diagnosis may be late or neglected due to the great clinical spectrum of symptoms, various forms of initial presentation and unspecific signs of neuroimaging. Materials and methods: In this descriptive study, the included patients were followed up according to clinical manifestations, diagnostic efforts and clinical suspicions. The information regarding the subjects’ age, gender, clinical presentation, diagnostic efforts and classified treatment results were recorded. The data was obtained during a 21 months period and analyzed in SPSS. Results: The most prevalent symptoms among the study population were headache, papillary edema, blurred vision, sensory-motor disorder, disorders of consciousness, double vision, behavioral disorder, speech impairment, focal seizure, and generalized seizure. The most common reasons were taking oral contraceptive pill (OCP), pregnancy, infection, idiopathic, drug abuse, hematologic diseases, trauma, previous cerebrovascular accident, CVT, diabetes, and hypertension. Conclusion: The most prevalent complaint was headache and the most founded neurological sign was papillary edema.
