Male, 61 years old, with weakness. Assess for CNS metastases versus ischemia. A punctate focus of mild diffusion bright signal is seen within the right globus pallidus with equivocal ADC correlation. No other definite areas of restricted diffusion are seen.Moderate patchy T2 hyperintensity is seen within the subcortical and periventricular regions as well as the pons. No evidence of mass effect or parenchymal edema is seen. No significant intracranial hemorrhage or any abnormal extra axial fluid collection is detected. The ventricles are normal in size and morphology.On postcontrast images no pathologic parenchymal or extra-axial enhancement is detected.A few scattered small nonspecific T2 hyperintense enhancing skull lesions are demonstrated.
1.Moderate chronic small vessel ischemic disease.2.No definite evidence of acute ischemia. A punctate focus of questionable diffusion signal abnormality within the right globus pallidus is nonspecific and may simply be artifactual.3.No evidence of intracranial metastases.
