Objective To investigate the clinical features and imaging findings of 30 cases of patients with intracranial venous sinus thrombosis, and to improve the understanding of the disease. Methods The clinical features and imaging findings of 30 patients with intracranial venous sinus thrombosis were retrospectively analyzed. Results Among the 30 patients, the morbidity of CVST in 31-50 year-old patients was the highest,. The 30 cases were given CT scan, which showed that there was abnormity in 16 cases, including 3 cases of diffuse brain edema, with empty triangle sign, 5 cases of brain parenchyma low- density shadow; 2 cases with high-density shadow in the diseased venous sinus. MRI scan was performed in 27 cases, which showed that there were 22 cases of abnormal brain signal, including 8 cases of unilateral lesions and 14 cases of bilateral lesions. The main features were cerebral infarction and cerebral edema. 26 cases of MRV examination showed that there were different degrees of sinus venous diseases and the main performance was affected sinus venous not developing or not clearly developing. DSA examination showed that there were different degrees of sinus venous congestion. Conclusion The cause of CVST is complex and the clinical symptoms are different. Patients with suspected CVST should receive CT, MRI, MRV and other imaging examinations to diagnose the disease, and to receive early individualized treatment, which can improve the prognosis of the disease.
