Metastatic lung cancer with brain mets treated with WBRT and SRS, now on Docetaxel now. There is a persistent punctate focus of susceptibility effect in the right postcentral gyrus, but no evidence of enhancing intracranial lesions. There is unchanged confluent white matter T2 hyperintensity in the bilateral cerebral hemispheres, which is likely treatment-related. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is persistent mild scattered paranasal sinus mucosal thickening and fluid signal within the bilateral mastoid air cells.
Persistent punctate susceptibility effect in the right postcentral gyrus without evidence of residual enhancing metastases superimposed on a background of whole brain radiation effects.
