Male, 67 years old, history of CNS lymphoma, restaging examination. No evidence of pathologic enhancement, restricted diffusion or other new parenchymal signal abnormal is seen. Patchy T2 hyperintensity is again demonstrated in the bilateral basal ganglia, periventricular white matter, and the left lateral cerebellum, most which probably corresponds to sites of prior lymphomatous disease. No evidence of any new parenchymal edema or mass effect is seen. The ventricular system is stable in size and morphology including asymmetry with the left lateral ventricle larger than the right. No pathologic intracranial fluid collections are seen. No evidence of acute intracranial hemorrhage is noted.
1. No findings are seen to suggest new or recurrent intracranial lymphomatous disease.2. Scattered patchy areas of parenchymal signal abnormality are redemonstrated, perhaps representing a combination of sites of prior lymphomatous disease and some superimposed chronic microvascular ischemia.
