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 of 6 patients with subependymomas proved by surgical pathology, observed from January 2007 to June 2013, were analyzed retrospectively. Results Six patients (4 males and 2 females) presented with headache and dizziness. Among these 6 patients, tumor developed in right lateral ventri-cle in three patients, in left lateral ventricle in 2 patients 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.
