[Subependymoma of the lateral ventricle: a case report].
We report a case of subependymoma of the right lateral ventricle in a 59-year-old man. CT revealed a mass lesion in the right lateral ventricle. No calcification was seen in the tumor, and the right lateral ventricle was dilated dominantly by the tumor. The tumor showed intermediate intensity on T1-weighted MR images and high intensity on T2-weighted MR images. On contrast study, the tumor showed heterogeneous enhancement. We suspected this to be a case of central neurocytoma, and surgical resection was performed. The histological diagnosis was subependymoma, but we considered it difficult to differentiate from astrocytoma, central neurocytoma, and ependymoma.
