Malignant neoplasm of bronchus and lung. There has been overall decrease in size of multiple brain metastases since January 2015. For example, the dominant left temporal lobe lesion measures up to 22 x 20 mm, previously 25 x 24 mm and a right cerebellar lesion measures 9 x 9 mm, previously 11 x 12 mm. However, a left superior frontal gyrus lesion that measures up to 4 mm is not significantly changed. There has also been slight interval decrease in the associated vasogenic edema and midline shift, now measuring up to 7 mm, previously 9 mm. There is persistent partial effacement of the left lateral and third ventricles, but no evidence of hydrocephalus. 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.
