Metastatic lung cancer with treated brain metastases. Please compare to outside MRI 4/1/2015 to evaluate disease status. There is redemonstration of the scattered foci of intrinsic T1 shortening involving the medial right superior frontal gyrus, posterior right superior frontal gyrus, right inferior parietal lobule, left precentral gyrus, and left medial thalamus. No other abnormal enhancing lesion is identified. There is no evidence of acute intracranial hemorrhage, mass effect, or acute infarct. There are scattered punctate foci and confluent areas of abnormal T2/FLAIR hyperintensity within the periventricular and subcortical white matter. Many of these lesions demonstrate a morphology and distribution often seen with demyelinating disease. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable.
1.No significant interval change in multiple scattered foci of intrinsic T1 shortening as described above, compared to 2/26/2015. No findings to suggest progression of metastatic disease.2.Scattered T2 hyperintense lesions in the white matter, which are nonspecific and unchanged. Differential considerations include chronic demyelinating (favored), inflammatory, or ischemic etiology. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
