Chordoid Glioma:MRI Findings with Pathologic Correlations
Objective To analyze the MRI findings of chordoid gliomas and to compare with pathology in order to improve the understanding and preoperative diagnosis of the disease.Methods The clinical,MRI,and pathological data of 7 cases of chordoid gliomas confirmed by surgery and pathology were retrospectively analyzed.Results Of the 7 patients,3 were male and 4 were female,aged 27-56 years,with an average age of(41±9.2)years.All of the 7 lesions were located from the anterior third ventricle to the suprasellar region,and 5 were completely solid.The main body of the lesions was solid with multiple small cystic areas at the edge of the lesion in 2 cases.On enhanced scan,the cystic areas of the lesions were not enhanced,while the solid parts showed significant enhancement like all tumors.PWI lesions showed high perfusion.The Cho peak in the solid area of the MRS lesions increased,and the NAA peak decreased.Conclusion MRI findings of chordoid gliomas have certain characteristics.Comprehensive analysis of lesion location,signal and enhancement features,ombined with the manifestations of PWI and MRS,the preoperative diagnosis of thie disease can be improved.
