Report of one case of a oligodendroglioma with an arteriovenous malformation and review of literature related to them

Objective:To enhance the understanding of such disease by reporting of one case of a oligodendroglioma with an arteriovenous malformation and review of literature.Methods:The clinical data of this patient in our hospital was analyzed retrospectively.The literatures related to such disease were reviewed,The clinical manifestations,imaging findings and the mechanism of the disease were discussed.Results: The patient diagnosed as intracranial space-occupying lesions,the MRI showed that slightly longer T1 and long T2 signal foci at right side of the parietal and occipital lobe,the boundaries of the lesions were less clear and they were slightly enhanced.MRA showed no abnormal vessels.They were seen during the surgery that the lesions looked purple vascular lumps,their borders were clear.Conclusion:The case of a oligodendroglioma with an arteriovenous malformation is extremely rare,the arteriovenous malformation are easily missed preoperatively,so the cerebral angiography can be help to diagnosis and to reduce the risk of surgery.
