This axial (cross section) contrast enhanced T1 weighted MRI shows a well circumscribed, non-enhancing mass within the lateral ventricle with an attachment to the septum pellucidum. The mass demonstrates decreased T1 signal with some mild heterogeneity. This is the typical appearance of a Subependymoma, a benign variant of the ependymoma tumours which is often seen as an incidental finding in the elderly.
