Analysis of Clinical Manifestations and CT and MRI Findings of Venous Cerebral Embolism

Objective: To investigate the pathogenesis, clinical manifestations, CT and magnetic resonance imaging(MRI) findings of patients with venous cerebral embolism. Methods: The clinical data of 8 patients(12 lesions) diagnosed by clinical and imaging combined examination was retrospectively analyzed. Among them, 6 patients underwent MRI enhanced scan and some patients underwent surgical treatment. The results of CT scan and MRI sequence examination were analyzed before and after treatment, and their imaging findings were evaluated. Results: Among the 8 diagnosed patients, 6 cases were diagnosed with superficial venous thrombosis(5 cases were unilateral and 1 case was bilateral). The clinical manifestations were headache, nausea, vomiting, focal neurological deficits or seizures; there were 2 cases with deep central venous thrombosis(unilateral/bilateral thalamus venous infarction in basal ganglia in 1 case respectively). The clinical manifestations were mild and the progression of pathogenic condition was slow. The prognosis was ideal. CT plain scan of 12 lesions showed low density shadow; T1 WI image showed low signal while DWI image showed high signal. T2 WI image showed high signal in 9 and mixed signal in 3; The 8 lesions in 6 cases undergoing enhanced MRI scan showed enhanced ring and thickness was homogeneous, irregular. Conclusions: Compared with CT examination, MRI can help doctors to understand the information of lesions in patients with venous cerebral embolism more directly and clearly, which has positive effect on the development of targeted therapy and the accurate assessment of prognosis.
