Metastatic lung cancer, brain mets, no therapy to brain lesions. EGFR/T790M+, on Tagrisso therapy. There is slight interval increase in size of several enhancing supratentorial lesions. For example, a right superior frontal sulcus lesion measures up to 8 mm, previously 6 mm. However, some lesions are unchanged or slightly smaller, such as a punctate lesion in the medial right occipital lobe. Furthermore, there is no evidence of residual cerebellar lesions. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Interval increase in size of several enhancing supratentorial lesions. Other lesions are not significantly changed or smaller.
