Right retinoblastoma with abnormal anterior eye segment enhancement: iris neovascularization. Note postlaminar optic nerve invasion in sagittal MR image. Postcontrast axial MR image of both orbits with fat suppression (a) and sagittal MR image of right orbit (b) shows heterogeneous enhancement of the right retinoblastoma and extreme enhancement of the iris of the right eye compared to that of the left eye ( red arrow). Note the abnormal enhancement of the distal optic nerve (sagittal MR images of the right orbit) indicative of postlaminar optic nerve invasion. Maximum axial diameter of right retinoblastoma 1.9 cm
