Analysis of imaging characteristics of patients with cerebral vein and sinus thrombosis

Objective To summarize the imaging features of patients with cerebral venous and sinus thrombosis (CVST). Methods The clinical data of 52 patients with CVST were retrospectively analyzed, and their imaging characteristics were analyzed. Results Of 52 patients, 3 received examination of CT+CTV, 16 of CT+MRI+MRV, 30 of MRI+MRV, and 3 of CT+DSA. The CT imags showed 5 high-density triangle sign, 9 high-density point sign, 4 band sign or strip sign. The MRI imags showed 18 intracranial venous system thrombosis signal. DSA showed 3 prolonged venous circulation, filling defect or non-development of intracranial venous system. After treatment, the clinical symptoms were gradually relieved in 42 patients and did not improve in 7, and 3 patients died; the images showed that the intracranial venous system was completely recanalized in 6 patients, and partially recannalized in 43. Conclusion Imaging examination can find the direct features of CVST, which is helpful for the early diagnosis of CVST.
