Female, 79 years old, altered mental status. Assess for recurrent breast cancer. No evidence of parenchymal edema or any discrete mass or pathologic enhancement is seen to suggest the presence of intracranial metastatic disease.Numerous subcortical and periventricular foci of T2 hyperintensity are seen, a nonspecific finding which likely reflects chronic microvascular ischemic disease. No restricted diffusion is detected to suggest acute ischemia.No significant intracranial hemorrhage is suspected. There is a single small focus of susceptibility within the left frontal white matter which probably reflects chronic microhemorrhage. No abnormal extra-axial fluid collections are present. Ventricles are normal in size and morphology.
1.No evidence of intracranial metastases.2.Chronic microvascular ischemic disease.
