Brain metastasis status post surgery and radiation. Surveillance exam. There are postoperative findings related to frontal craniotomy. There is a persistent punctate focus of enhancement in the anterior right superior frontal gyrus with surrounding vasogenic edema. There is no definite evidence of additional enhancing lesions, although the images are degraded by motion artifact. 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 are grossly unremarkable. There is a small right sphenoid sinus retention cyst.
Post-treatment findings with a persistent nonspecific small area of enhancement in the anterior right superior frontal gyrus with surrounding vasogenic edema. There is no definite evidence of additional enhancing intracranial lesions, although the images are degraded by motion artifact.
