Central neurocytoma, a cerebral intraventricular tumor, is usually benign. It frequently develops in the area of the foramen of Monro, and is usually attached to the septum pellucidum. Mild to moderate contrast enhancement is common. We encountered a case of central neurocytoma in a 60-year-old woman; the tumor arose from the atrium of the lateral ventricle, and extraventricular extension and malignant transformation were apparent. CT and MRI revealed a well-defined, slightly heterogeneous mass measuring 2.5x3x5cm with surrounding edema. There was strong contrast enhancement of the mass.

Venous aneurysm of the superior vena cava(SVC) is a rare congenital lesion and can be classified morphologically as either fusiform or saccular. Although there is a controversy with regard to the need for either conservative or surgical treatment, surgery is recommended for the saccular type as major complications of the aneurysm may occur. We report a case of saccular aneurysm of the SVC, treated by means of an endoluminal stent-graft.
