Abstract:
Objective To analyze the clinical,imaging and pathological features of cortical vein thrombosis (CoVT). Methods Ten patients with CoVT (4 patients with CoVT alone and 6 patients with CoVT and venous sinus thrombosis)treated at Navy General Hospital from January 2006 to Jun 2013 were collected retrospectively.Its etiology,imaging,and pathological features of brain tissue in 3 patients were analyzed. Results Of the 10 patients with CoVT,3 were female and 7 were male.Their mean age was 31 ± 15 years old.(1)Brain CT scan and MRI showed hemorrhagic cerebral infarction,and contrast-enhanced MRI showed scattered heterogeneous enhancement within lesions. DSA could find CoVT at different parts.(2)3 patients underwent brain biopsy because they were initially diagnosed as brain tumor. Pathological examination showed glial cell,endothelial proliferation and phagocytic reaction.Scattered spotty bleeding was observed,and significant expansion of small veins,A few of them had blood stasis and thrombosis. Conclusion CoVT is one kind of intracranial venous thrombosis. It is more common occurred in young and middle aged adults,and most of them were venous sinus thrombosis.It is caused by retrograde thrombosis and spread to cortical veins.CoVT is easily to be misdiagnosed as brain tumor.Combination of clinical and imaging findings is needed for accurate diagnosis.
