ABSTRACT
Objective To investigate MRI features of cystic oligodendrocytoma.Methods MRI features of 10 patients with oligodendroglial tumors proved with operation and pathology were analyzed retrospectively.Results Among 10 patients,lesionslocated on the supratentorium in 8 patients,while on the cerebellar vermis in 2 patients.Solitary lesion was found in 9 cases,and multiple lesions were found in 1 case.Complete cystic lesions were observed in 4 cases,large cystic lesions with solid nodules were found in 3 cases,and multi-cystic lesions were found in 3 cases.Smooth cyst wall of lesions were found in 7 cases,locally depressed and rough wall were found in 3 cases.Calcifications were found in 3 cases.Mild peritumoral edema was found in 9 cases,moderate to severe edema was found in 1 case.The lesions significantly enhanced in 3 cases,ring enhanced in 3 cases,and locally enhanced in 1 case.Conclusion COD is difficult to diagnose,but has certain MRI characteristics.COD should be considered when supratentorial complete cystic lesion or large cystic lesion with septum and/or solid nodule was found with MRI.
