Abstract:

[Abstract] Objective Analysis of MRI image of lateral ventricular subependymomas to improve our recognition of radiology manifestation of the disease.Methods Clinical data and MRI findings of6patients with subependymomas proved by surgical pathology, observed from January2007to June 2013, were analyzed retrospectively. Results Six patients (4 males and2females) presented with headache and dizziness. Among these 6patients, tumor developed in right lateral ventri? cle in three patients, in left lateral ventricle in2patients and in frontal of dual lateral ventricle in one patient. In MRI image, tumors showed iso- intense to hypointense to normal white matter on T1- weighted and DWI images, hyperintense on T2- weighted and FLAIR. Mild or no enhancement was noted in most cases. MRS showed findings consistent with low-grade tu? mor, with a normal choline peak and depressed N-acetyl-aspartate peak.Conclusion Lateral ventricular subependymo? mas have characteristic MRI features and multi-direction images are helpful for diagnosis.
