Nausea with vomiting, unspecified [R11.2], Reason for Study: ^Reason: NSCLC mets to brain with bulky dz and hz of radiation (last in 12/2015), now with intractable nausea/vomiting History: nausea/vomiting There are significant interval decrease in size as well as the extent of surrounding edema of all previously seen intra axial enhancing lesions since prior scan including the right corpus callosum splenium lesion and multiple left cerebellar hemispheric lesions.Those lesions demonstrate susceptibility artifacts indicating the nature of those lesions contain internal hemorrhages. No evidence of acute ischemic or hemorrhagic lesion. There is no evidence of new enhancing lesion. The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The left frontal sinus shows fluid collections.Bilateral mastoid air cells demonstrate fluid collections.
1. Interval decrease in size and the extent of surrounding edema on previously seen intra axial metastatic lesions since prior scan indicating interval improvement.2. No new metastatic lesion is found.3. No evidence of acute ischemic or hemorrhagic lesion.
