Male, 63 years old, with newly diagnosed lung cancer. Evaluate for brain metastases. No evidence of restricted diffusion, edema or mass effect is seen. Scattered small foci of T2 hyperintensity are evident within the periventricular white matter bilaterally. No intracranial hemorrhage or any abnormal extra-axial fluid collections are detected. Ventricular size and morphology are within normal limits.
