59-year-old man with history of lung cancer, evaluate for brain metastases. There is an enhancing nodule in the left occipital cortex which now measures approximately 3 x 3 mm, previously 5 x 5 mm in 9/2016 and 9 x 9 mm in 5/2016. Additionally, there is a small focus of susceptibility corresponding to this lesion. No surrounding edema or significant mass effect.Enhancing, dural based nodule along the right planum sphenoidale is unchanged in size. There are no additional foci of abnormal enhancement. There are a few scattered foci of T2 hyperintensity in the cerebral white matter. 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. There is mild maxillary sinus mucosal thickening, right greater than left. The orbits, skull, and scalp soft tissues are grossly unremarkable.
1.Continued decrease in size of enhancing lesion in the left occipital cortex compatible with treated metastatic disease.2.Stable enhancing right planum sphenoidale lesion, likely a meningioma.
