Abstract:
Objective To explore the CT and MRI imaging features of brain parenchymal ependymoma.Methods A retrospective analysis was conducted on the CT and MRI findings of 16 cases of brain parenchymal ependymoma confirmed by surgery and compared with pathological findings.The imaging features(including size,morphology,cyst separation,solid components,peritumoral edema and degree of enhancement,etc)were analyzed.Results Fourteen cases located in the cerebral hemisphere,2 cases located in the cerebellum.All 16 cases of lesions were solitary,1 case with a regular shape and 15 cases with an irregular shape.The lesions with a larger volume were in the deep white matter adjacent to the lateral ventricle.Heterogeneous CT and MRI lesions with multiple cystic changes located inside and around the lesion.There was hemorrhage inside the anaplastic ependymoma.The solid components and cyst wall showed significant enhancement on enhanced scanning.Conclusion The pathological grading of brain parenchymal ependymoma determined its imaging features.It is characterized by internal and peripheral large cysts and nodular calcification.
